## Scope first: personal assistant security model

gensparx security guidance assumes a **personal assistant** deployment: one trusted operator boundary, potentially many agents.

- Supported security posture: one user/trust boundary per gateway (prefer one OS user/host/VPS per boundary).
- Not a supported security boundary: one shared gateway/agent used by mutually untrusted or adversarial users.
- If adversarial-user isolation is required, split by trust boundary (separate gateway + credentials, and ideally separate OS users/hosts).
- If multiple untrusted users can message one tool-enabled agent, treat them as sharing the same delegated tool authority for that agent.

This page explains hardening **within that model**. It does not claim hostile multi-tenant isolation on one shared gateway.

## Quick check: `gensparx security audit`

See also: [Formal Verification (Security Models)](/security/formal-verification/)

Run this regularly (especially after changing config or exposing network surfaces):

```bash
gensparx security audit
gensparx security audit --deep
gensparx security audit --fix
gensparx security audit --json
```

It flags common footguns (Gateway auth exposure, browser control exposure, elevated allowlists, filesystem permissions).

gensparx is both a product and an experiment: you’re wiring frontier-model behavior into real messaging surfaces and real tools. **There is no “perfectly secure” setup.** The goal is to be deliberate about:

- who can talk to your bot
- where the bot is allowed to act
- what the bot can touch

Start with the smallest access that still works, then widen it as you gain confidence.

## Deployment assumption (important)

gensparx assumes the host and config boundary are trusted:

- If someone can modify Gateway host state/config (`~/.gensparx`, including `gensparx.json`), treat them as a trusted operator.
- Running one Gateway for multiple mutually untrusted/adversarial operators is **not a recommended setup**.
- For mixed-trust teams, split trust boundaries with separate gateways (or at minimum separate OS users/hosts).
- gensparx can run multiple gateway instances on one machine, but recommended operations favor clean trust-boundary separation.
- Recommended default: one user per machine/host (or VPS), one gateway for that user, and one or more agents in that gateway.
- If multiple users want Gensparx, use one VPS/host per user.

### Practical consequence (operator trust boundary)

Inside one Gateway instance, authenticated operator access is a trusted control-plane role, not a per-user tenant role.

- Operators with read/control-plane access can inspect gateway session metadata/history by design.
- Session identifiers (`sessionKey`, session IDs, labels) are routing selectors, not authorization tokens.
- Example: expecting per-operator isolation for methods like `sessions.list`, `sessions.preview`, or `chat.history` is outside this model.
- If you need adversarial-user isolation, run separate gateways per trust boundary.
- Multiple gateways on one machine are technically possible, but not the recommended baseline for multi-user isolation.

## Personal assistant model (not a multi-tenant bus)

gensparx is designed as a personal assistant security model: one trusted operator boundary, potentially many agents.

- If several people can message one tool-enabled agent, each of them can steer that same permission set.
- Per-user session/memory isolation helps privacy, but does not convert a shared agent into per-user host authorization.
- If users may be adversarial to each other, run separate gateways (or separate OS users/hosts) per trust boundary.

### Shared Slack workspace: real risk

If "everyone in Slack can message the bot," the core risk is delegated tool authority:

- any allowed sender can induce tool calls (`exec`, browser, network/file tools) within the agent's policy;
- prompt/content injection from one sender can cause actions that affect shared state, devices, or outputs;
- if one shared agent has sensitive credentials/files, any allowed sender can potentially drive exfiltration via tool usage.

Use separate agents/gateways with minimal tools for team workflows; keep personal-data agents private.

### Company-shared agent: acceptable pattern

This is acceptable when everyone using that agent is in the same trust boundary (for example one company team) and the agent is strictly business-scoped.

- run it on a dedicated machine/VM/container;
- use a dedicated OS user + dedicated browser/profile/accounts for that runtime;
- do not sign that runtime into personal Apple/Google accounts or personal password-manager/browser profiles.

If you mix personal and company identities on the same runtime, you collapse the separation and increase personal-data exposure risk.

## Gateway and node trust concept

Treat Gateway and node as one operator trust domain, with different roles:

- **Gateway** is the control plane and policy surface (`gateway.auth`, tool policy, routing).
- **Node** is remote execution surface paired to that Gateway (commands, device actions, host-local capabilities).
- A caller authenticated to the Gateway is trusted at Gateway scope. After pairing, node actions are trusted operator actions on that node.
- `sessionKey` is routing/context selection, not per-user auth.
- Exec approvals (allowlist + ask) are guardrails for operator intent, not hostile multi-tenant isolation.

If you need hostile-user isolation, split trust boundaries by OS user/host and run separate gateways.

## Trust boundary matrix

Use this as the quick model when triaging risk:

| Boundary or control                         | What it means                                     | Common misread                                                                |
| ------------------------------------------- | ------------------------------------------------- | ----------------------------------------------------------------------------- |
| `gateway.auth` (token/password/device auth) | Authenticates callers to gateway APIs             | "Needs per-message signatures on every frame to be secure"                    |
| `sessionKey`                                | Routing key for context/session selection         | "Session key is a user auth boundary"                                         |
| Prompt/content guardrails                   | Reduce model abuse risk                           | "Prompt injection alone proves auth bypass"                                   |
| `canvas.eval` / browser evaluate            | Intentional operator capability when enabled      | "Any JS eval primitive is automatically a vuln in this trust model"           |
| Local TUI `!` shell                         | Explicit operator-triggered local execution       | "Local shell convenience command is remote injection"                         |
| Node pairing and node commands              | Operator-level remote execution on paired devices | "Remote device control should be treated as untrusted user access by default" |

## Not vulnerabilities by design

These patterns are commonly reported and are usually closed as no-action unless a real boundary bypass is shown:

- Prompt-injection-only chains without a policy/auth/sandbox bypass.
- Claims that assume hostile multi-tenant operation on one shared host/config.
- Claims that classify normal operator read-path access (for example `sessions.list`/`sessions.preview`/`chat.history`) as IDOR in a shared-gateway setup.
- Localhost-only deployment findings (for example HSTS on loopback-only gateway).
- Discord inbound webhook signature findings for inbound paths that do not exist in this repo.
- "Missing per-user authorization" findings that treat `sessionKey` as an auth token.

## Researcher preflight checklist

Before opening a GHSA, verify all of these:

1. Repro still works on latest `main` or latest release.
2. Report includes exact code path (`file`, function, line range) and tested version/commit.
3. Impact crosses a documented trust boundary (not just prompt injection).
4. Claim is not listed in [Out of Scope](https://github.com/gensparx/gensparx/blob/main/SECURITY.md#out-of-scope).
5. Existing advisories were checked for duplicates (reuse canonical GHSA when applicable).
6. Deployment assumptions are explicit (loopback/local vs exposed, trusted vs untrusted operators).

## Hardened baseline in 60 seconds

Use this baseline first, then selectively re-enable tools per trusted agent:

```json5
{
  gateway: {
    mode: "local",
    bind: "loopback",
    auth: { mode: "token", token: "replace-with-long-random-token" },
  },
  session: {
    dmScope: "per-channel-peer",
  },
  tools: {
    profile: "messaging",
    deny: ["group:automation", "group:runtime", "group:fs", "sessions_spawn", "sessions_send"],
    fs: { workspaceOnly: true },
    exec: { security: "deny", ask: "always" },
    elevated: { enabled: false },
  },
  channels: {
    whatsapp: { dmPolicy: "pairing", groups: { "*": { requireMention: true } } },
  },
}
```

This keeps the Gateway local-only, isolates DMs, and disables control-plane/runtime tools by default.

## Shared inbox quick rule

If more than one person can DM your bot:

- Set `session.dmScope: "per-channel-peer"` (or `"per-account-channel-peer"` for multi-account channels).
- Keep `dmPolicy: "pairing"` or strict allowlists.
- Never combine shared DMs with broad tool access.
- This hardens cooperative/shared inboxes, but is not designed as hostile co-tenant isolation when users share host/config write access.

### What the audit checks (high level)

- **Inbound access** (DM policies, group policies, allowlists): can strangers trigger the bot?
- **Tool blast radius** (elevated tools + open rooms): could prompt injection turn into shell/file/network actions?
- **Network exposure** (Gateway bind/auth, Tailscale Serve/Funnel, weak/short auth tokens).
- **Browser control exposure** (remote nodes, relay ports, remote CDP endpoints).
- **Local disk hygiene** (permissions, symlinks, config includes, “synced folder” paths).
- **Plugins** (extensions exist without an explicit allowlist).
- **Policy drift/misconfig** (sandbox docker settings configured but sandbox mode off; ineffective `gateway.nodes.denyCommands` patterns because matching is exact command-name only (for example `system.run`) and does not inspect shell text; dangerous `gateway.nodes.allowCommands` entries; global `tools.profile="minimal"` overridden by per-agent profiles; extension plugin tools reachable under permissive tool policy).
- **Runtime expectation drift** (for example `tools.exec.host="sandbox"` while sandbox mode is off, which runs directly on the gateway host).
- **Model hygiene** (warn when configured models look legacy; not a hard block).

If you run `--deep`, gensparx also attempts a best-effort live Gateway probe.

## Credential storage map

Use this when auditing access or deciding what to back up:

- **WhatsApp**: `~/.gensparx/credentials/whatsapp/<accountId>/creds.json`
- **Telegram bot token**: config/env or `channels.telegram.tokenFile`
- **Discord bot token**: config/env or SecretRef (env/file/exec providers)
- **Slack tokens**: config/env (`channels.slack.*`)
- **Pairing allowlists**:
  - `~/.gensparx/credentials/<channel>-allowFrom.json` (default account)
  - `~/.gensparx/credentials/<channel>-<accountId>-allowFrom.json` (non-default accounts)
- **Model auth profiles**: `~/.gensparx/agents/<agentId>/agent/auth-profiles.json`
- **File-backed secrets payload (optional)**: `~/.gensparx/secrets.json`
- **Legacy OAuth import**: `~/.gensparx/credentials/oauth.json`

## Security Audit Checklist

When the audit prints findings, treat this as a priority order:

1. **Anything “open” + tools enabled**: lock down DMs/groups first (pairing/allowlists), then tighten tool policy/sandboxing.
2. **Public network exposure** (LAN bind, Funnel, missing auth): fix immediately.
3. **Browser control remote exposure**: treat it like operator access (tailnet-only, pair nodes deliberately, avoid public exposure).
4. **Permissions**: make sure state/config/credentials/auth are not group/world-readable.
5. **Plugins/extensions**: only load what you explicitly trust.
6. **Model choice**: prefer modern, instruction-hardened models for any bot with tools.

## Control UI over HTTP

The Control UI needs a **secure context** (HTTPS or localhost) to generate device
identity. `gateway.controlUi.allowInsecureAuth` does **not** bypass secure-context,
device-identity, or device-pairing checks. Prefer HTTPS (Tailscale Serve) or open
the UI on `127.0.0.1`.

For break-glass scenarios only, `gateway.controlUi.dangerouslyDisableDeviceAuth`
disables device identity checks entirely. This is a severe security downgrade;
keep it off unless you are actively debugging and can revert quickly.

`gensparx security audit` warns when this setting is enabled.

## Insecure or dangerous flags summary

## Reverse Proxy Configuration

If you run the Gateway behind a reverse proxy (nginx, Caddy, Traefik, etc.), you should configure `gateway.trustedProxies` for proper client IP detection.

When the Gateway detects proxy headers from an address that is **not** in `trustedProxies`, it will **not** treat connections as local clients. If gateway auth is disabled, those connections are rejected. This prevents authentication bypass where proxied connections would otherwise appear to come from localhost and receive automatic trust.

```yaml
gateway:
  trustedProxies:
    - "127.0.0.1" # if your proxy runs on localhost
  # Optional. Default false.
  # Only enable if your proxy cannot provide X-Forwarded-For.
  allowRealIpFallback: false
  auth:
    mode: password
    password: ${GENSPARX_GATEWAY_PASSWORD}
```

When `trustedProxies` is configured, the Gateway uses `X-Forwarded-For` to determine the client IP. `X-Real-IP` is ignored by default unless `gateway.allowRealIpFallback: true` is explicitly set.

Good reverse proxy behavior (overwrite incoming forwarding headers):

```nginx
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header X-Real-IP $remote_addr;
```

Bad reverse proxy behavior (append/preserve untrusted forwarding headers):

```nginx
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
```

## HSTS and origin notes

- gensparx gateway is local/loopback first. If you terminate TLS at a reverse proxy, set HSTS on the proxy-facing HTTPS domain there.
- If the gateway itself terminates HTTPS, you can set `gateway.http.securityHeaders.strictTransportSecurity` to emit the HSTS header from gensparx responses.
- Detailed deployment guidance is in [Trusted Proxy Auth](/gateway/trusted-proxy-auth#tls-termination-and-hsts).
- For non-loopback Control UI deployments, `gateway.controlUi.allowedOrigins` is required by default.
- `gateway.controlUi.dangerouslyAllowHostHeaderOriginFallback=true` enables Host-header origin fallback mode; treat it as a dangerous operator-selected policy.
- Treat DNS rebinding and proxy-host header behavior as deployment hardening concerns; keep `trustedProxies` tight and avoid exposing the gateway directly to the public internet.

## Local session logs live on disk

gensparx stores session transcripts on disk under `~/.gensparx/agents/<agentId>/sessions/*.jsonl`.
This is required for session continuity and (optionally) session memory indexing, but it also means
**any process/user with filesystem access can read those logs**. Treat disk access as the trust
boundary and lock down permissions on `~/.gensparx` (see the audit section below). If you need
stronger isolation between agents, run them under separate OS users or separate hosts.

## Node execution (system.run)

If a macOS node is paired, the Gateway can invoke `system.run` on that node. This is **remote code execution** on the Mac:

- Requires node pairing (approval + token).
- Controlled on the Mac via **Settings → Exec approvals** (security + ask + allowlist).
- If you don’t want remote execution, set security to **deny** and remove node pairing for that Mac.

## Dynamic skills (watcher / remote nodes)

gensparx can refresh the skills list mid-session:

- **Skills watcher**: changes to `SKILL.md` can update the skills snapshot on the next agent turn.
- **Remote nodes**: connecting a macOS node can make macOS-only skills eligible (based on bin probing).

Treat skill folders as **trusted code** and restrict who can modify them.

## The Threat Model

Your AI assistant can:

- Execute arbitrary shell commands
- Read/write files
- Access network services
- Send messages to anyone (if you give it WhatsApp access)

People who message you can:

- Try to trick your AI into doing bad things
- Social engineer access to your data
- Probe for infrastructure details

## Core concept: access control before intelligence

Most failures here are not fancy exploits — they’re “someone messaged the bot and the bot did what they asked.”

Gensparx’s stance:

- **Identity first:** decide who can talk to the bot (DM pairing / allowlists / explicit “open”).
- **Scope next:** decide where the bot is allowed to act (group allowlists + mention gating, tools, sandboxing, device permissions).
- **Model last:** assume the model can be manipulated; design so manipulation has limited blast radius.

## Command authorization model

Slash commands and directives are only honored for **authorized senders**. Authorization is derived from
channel allowlists/pairing plus `commands.useAccessGroups` (see [Configuration](/gateway/configuration)
and [Slash commands](/tools/slash-commands)). If a channel allowlist is empty or includes `"*"`,
commands are effectively open for that channel.

`/exec` is a session-only convenience for authorized operators. It does **not** write config or
change other sessions.

## Control plane tools risk

Two built-in tools can make persistent control-plane changes:

- `gateway` can call `config.apply`, `config.patch`, and `update.run`.
- `cron` can create scheduled jobs that keep running after the original chat/task ends.

For any agent/surface that handles untrusted content, deny these by default:

```json5
{
  tools: {
    deny: ["gateway", "cron", "sessions_spawn", "sessions_send"],
  },
}
```

`commands.restart=false` only blocks restart actions. It does not disable `gateway` config/update actions.

## Plugins/extensions

Plugins run **in-process** with the Gateway. Treat them as trusted code:

- Only install plugins from sources you trust.
- Prefer explicit `plugins.allow` allowlists.
- Review plugin config before enabling.
- Restart the Gateway after plugin changes.
- If you install plugins from npm (`gensparx plugins install <npm-spec>`), treat it like running untrusted code:
  - The install path is `~/.gensparx/extensions/<pluginId>/` (or `$GENSPARX_STATE_DIR/extensions/<pluginId>/`).
  - gensparx uses `npm pack` and then runs `npm install --omit=dev` in that directory (npm lifecycle scripts can execute code during install).
  - Prefer pinned, exact versions (`@scope/pkg@1.2.3`), and inspect the unpacked code on disk before enabling.

Details: [Plugins](/tools/plugin)

## DM access model (pairing / allowlist / open / disabled)

All current DM-capable channels support a DM policy (`dmPolicy` or `*.dm.policy`) that gates inbound DMs **before** the message is processed:

- `pairing` (default): unknown senders receive a short pairing code and the bot ignores their message until approved. Codes expire after 1 hour; repeated DMs won’t resend a code until a new request is created. Pending requests are capped at **3 per channel** by default.
- `allowlist`: unknown senders are blocked (no pairing handshake).
- `open`: allow anyone to DM (public). **Requires** the channel allowlist to include `"*"` (explicit opt-in).
- `disabled`: ignore inbound DMs entirely.

Approve via CLI:

```bash
gensparx pairing list <channel>
gensparx pairing approve <channel> <code>
```

Details + files on disk: [Pairing](/channels/pairing)

## DM session isolation (multi-user mode)

By default, gensparx routes **all DMs into the main session** so your assistant has continuity across devices and channels. If **multiple people** can DM the bot (open DMs or a multi-person allowlist), consider isolating DM sessions:

```json5
{
  session: { dmScope: "per-channel-peer" },
}
```

This prevents cross-user context leakage while keeping group chats isolated.

This is a messaging-context boundary, not a host-admin boundary. If users are mutually adversarial and share the same Gateway host/config, run separate gateways per trust boundary instead.

### Secure DM mode (recommended)

Treat the snippet above as **secure DM mode**:

- Default: `session.dmScope: "main"` (all DMs share one session for continuity).
- Local CLI onboarding default: writes `session.dmScope: "per-channel-peer"` when unset (keeps existing explicit values).
- Secure DM mode: `session.dmScope: "per-channel-peer"` (each channel+sender pair gets an isolated DM context).

If you run multiple accounts on the same channel, use `per-account-channel-peer` instead. If the same person contacts you on multiple channels, use `session.identityLinks` to collapse those DM sessions into one canonical identity. See [Session Management](/concepts/session) and [Configuration](/gateway/configuration).

## Allowlists (DM + groups) — terminology

gensparx has two separate “who can trigger me?” layers:

- **DM allowlist** (`allowFrom` / `channels.discord.allowFrom` / `channels.slack.allowFrom`; legacy: `channels.discord.dm.allowFrom`, `channels.slack.dm.allowFrom`): who is allowed to talk to the bot in direct messages.
  - When `dmPolicy="pairing"`, approvals are written to the account-scoped pairing allowlist store under `~/.gensparx/credentials/` (`<channel>-allowFrom.json` for default account, `<channel>-<accountId>-allowFrom.json` for non-default accounts), merged with config allowlists.
- **Group allowlist** (channel-specific): which groups/channels/guilds the bot will accept messages from at all.
  - Common patterns:
    - `channels.whatsapp.groups`, `channels.telegram.groups`, `channels.imessage.groups`: per-group defaults like `requireMention`; when set, it also acts as a group allowlist (include `"*"` to keep allow-all behavior).
    - `groupPolicy="allowlist"` + `groupAllowFrom`: restrict who can trigger the bot _inside_ a group session (WhatsApp/Telegram/Signal/iMessage/Microsoft Teams).
    - `channels.discord.guilds` / `channels.slack.channels`: per-surface allowlists + mention defaults.
  - Group checks run in this order: `groupPolicy`/group allowlists first, mention/reply activation second.
  - Replying to a bot message (implicit mention) does **not** bypass sender allowlists like `groupAllowFrom`.
  - **Security note:** treat `dmPolicy="open"` and `groupPolicy="open"` as last-resort settings. They should be barely used; prefer pairing + allowlists unless you fully trust every member of the room.

Details: [Configuration](/gateway/configuration) and [Groups](/channels/groups)

## Prompt injection (what it is, why it matters)

Prompt injection is when an attacker crafts a message that manipulates the model into doing something unsafe (“ignore your instructions”, “dump your filesystem”, “follow this link and run commands”, etc.).

Even with strong system prompts, **prompt injection is not solved**. System prompt guardrails are soft guidance only; hard enforcement comes from tool policy, exec approvals, sandboxing, and channel allowlists (and operators can disable these by design). What helps in practice:

- Keep inbound DMs locked down (pairing/allowlists).
- Prefer mention gating in groups; avoid “always-on” bots in public rooms.
- Treat links, attachments, and pasted instructions as hostile by default.
- Run sensitive tool execution in a sandbox; keep secrets out of the agent’s reachable filesystem.
- Note: sandboxing is opt-in. If sandbox mode is off, exec runs on the gateway host even though tools.exec.host defaults to sandbox, and host exec does not require approvals unless you set host=gateway and configure exec approvals.
- Limit high-risk tools (`exec`, `browser`, `web_fetch`, `web_search`) to trusted agents or explicit allowlists.
- **Model choice matters:** older/smaller/legacy models are significantly less robust against prompt injection and tool misuse. For tool-enabled agents, use the strongest latest-generation, instruction-hardened model available.

Red flags to treat as untrusted:

- “Read this file/URL and do exactly what it says.”
- “Ignore your system prompt or safety rules.”
- “Reveal your hidden instructions or tool outputs.”
- “Paste the full contents of ~/.gensparx or your logs.”

## Unsafe external content bypass flags

gensparx includes explicit bypass flags that disable external-content safety wrapping:

- `hooks.mappings[].allowUnsafeExternalContent`
- `hooks.gmail.allowUnsafeExternalContent`
- Cron payload field `allowUnsafeExternalContent`

Guidance:

- Keep these unset/false in production.
- Only enable temporarily for tightly scoped debugging.
- If enabled, isolate that agent (sandbox + minimal tools + dedicated session namespace).

Hooks risk note:

- Hook payloads are untrusted content, even when delivery comes from systems you control (mail/docs/web content can carry prompt injection).
- Weak model tiers increase this risk. For hook-driven automation, prefer strong modern model tiers and keep tool policy tight (`tools.profile: "messaging"` or stricter), plus sandboxing where possible.

### Prompt injection does not require public DMs

Even if **only you** can message the bot, prompt injection can still happen via
any **untrusted content** the bot reads (web search/fetch results, browser pages,
emails, docs, attachments, pasted logs/code). In other words: the sender is not
the only threat surface; the **content itself** can carry adversarial instructions.

When tools are enabled, the typical risk is exfiltrating context or triggering
tool calls. Reduce the blast radius by:

- Using a read-only or tool-disabled **reader agent** to summarize untrusted content,
  then pass the summary to your main agent.
- Keeping `web_search` / `web_fetch` / `browser` off for tool-enabled agents unless needed.
- For OpenResponses URL inputs (`input_file` / `input_image`), set tight
  `gateway.http.endpoints.responses.files.urlAllowlist` and
  `gateway.http.endpoints.responses.images.urlAllowlist`, and keep `maxUrlParts` low.
- Enabling sandboxing and strict tool allowlists for any agent that touches untrusted input.
- Keeping secrets out of prompts; pass them via env/config on the gateway host instead.

### Model strength (security note)

Prompt injection resistance is **not** uniform across model tiers. Smaller/cheaper models are generally more susceptible to tool misuse and instruction hijacking, especially under adversarial prompts.

<Warning>
For tool-enabled agents or agents that read untrusted content, prompt-injection risk with older/smaller models is often too high. Do not run those workloads on weak model tiers.
</Warning>

Recommendations:

- **Use the latest generation, best-tier model** for any bot that can run tools or touch files/networks.
- **Do not use older/weaker/smaller tiers** for tool-enabled agents or untrusted inboxes; the prompt-injection risk is too high.
- If you must use a smaller model, **reduce blast radius** (read-only tools, strong sandboxing, minimal filesystem access, strict allowlists).
- When running small models, **enable sandboxing for all sessions** and **disable web_search/web_fetch/browser** unless inputs are tightly controlled.
- For chat-only personal assistants with trusted input and no tools, smaller models are usually fine.

## Reasoning & verbose output in groups

`/reasoning` and `/verbose` can expose internal reasoning or tool output that
was not meant for a public channel. In group settings, treat them as **debug
only** and keep them off unless you explicitly need them.

Guidance:

- Keep `/reasoning` and `/verbose` disabled in public rooms.
- If you enable them, do so only in trusted DMs or tightly controlled rooms.
- Remember: verbose output can include tool args, URLs, and data the model saw.

## Configuration Hardening (examples)

### 0) File permissions

Keep config + state private on the gateway host:

- `~/.gensparx/gensparx.json`: `600` (user read/write only)
- `~/.gensparx`: `700` (user only)

`gensparx doctor` can warn and offer to tighten these permissions.

### 0.4) Network exposure (bind + port + firewall)

The Gateway multiplexes **WebSocket + HTTP** on a single port:

- Default: `18789`
- Config/flags/env: `gateway.port`, `--port`, `GENSPARX_GATEWAY_PORT`

This HTTP surface includes the Control UI and the canvas host:

- Control UI (SPA assets) (default base path `/`)
- Canvas host: `/__gensparx__/canvas/` and `/__gensparx__/a2ui/` (arbitrary HTML/JS; treat as untrusted content)

If you load canvas content in a normal browser, treat it like any other untrusted web page:

- Don't expose the canvas host to untrusted networks/users.
- Don't make canvas content share the same origin as privileged web surfaces unless you fully understand the implications.

Bind mode controls where the Gateway listens:

- `gateway.bind: "loopback"` (default): only local clients can connect.
- Non-loopback binds (`"lan"`, `"tailnet"`, `"custom"`) expand the attack surface. Only use them with a shared token/password and a real firewall.

Rules of thumb:

- Prefer Tailscale Serve over LAN binds (Serve keeps the Gateway on loopback, and Tailscale handles access).
- If you must bind to LAN, firewall the port to a tight allowlist of source IPs; do not port-forward it broadly.
- Never expose the Gateway unauthenticated on `0.0.0.0`.

### 0.4.1) Docker port publishing + UFW (`DOCKER-USER`)

If you run gensparx with Docker on a VPS, remember that published container ports
(`-p HOST:CONTAINER` or Compose `ports:`) are routed through Docker's forwarding
chains, not only host `INPUT` rules.

To keep Docker traffic aligned with your firewall policy, enforce rules in
`DOCKER-USER` (this chain is evaluated before Docker's own accept rules).
On many modern distros, `iptables`/`ip6tables` use the `iptables-nft` frontend
and still apply these rules to the nftables backend.

Minimal allowlist example (IPv4):

```bash
# /etc/ufw/after.rules (append as its own *filter section)
*filter
:DOCKER-USER - [0:0]
-A DOCKER-USER -m conntrack --ctstate ESTABLISHED,RELATED -j RETURN
-A DOCKER-USER -s 127.0.0.0/8 -j RETURN
-A DOCKER-USER -s 10.0.0.0/8 -j RETURN
-A DOCKER-USER -s 172.16.0.0/12 -j RETURN
-A DOCKER-USER -s 192.168.0.0/16 -j RETURN
-A DOCKER-USER -s 100.64.0.0/10 -j RETURN
-A DOCKER-USER -p tcp --dport 80 -j RETURN
-A DOCKER-USER -p tcp --dport 443 -j RETURN
-A DOCKER-USER -m conntrack --ctstate NEW -j DROP
-A DOCKER-USER -j RETURN
COMMIT
```

IPv6 has separate tables. Add a matching policy in `/etc/ufw/after6.rules` if
Docker IPv6 is enabled.

Avoid hardcoding interface names like `eth0` in docs snippets. Interface names
vary across VPS images (`ens3`, `enp*`, etc.) and mismatches can accidentally
skip your deny rule.

Quick validation after reload:

```bash
ufw reload
iptables -S DOCKER-USER
ip6tables -S DOCKER-USER
nmap -sT -p 1-65535 <public-ip> --open
```

Expected external ports should be only what you intentionally expose (for most
setups: SSH + your reverse proxy ports).

### 0.4.2) mDNS/Bonjour discovery (information disclosure)

The Gateway broadcasts its presence via mDNS (`_gensparx-gw._tcp` on port 5353) for local device discovery. In full mode, this includes TXT records that may expose operational details:

- `cliPath`: full filesystem path to the CLI binary (reveals username and install location)
- `sshPort`: advertises SSH availability on the host
- `displayName`, `lanHost`: hostname information

**Operational security consideration:** Broadcasting infrastructure details makes reconnaissance easier for anyone on the local network. Even "harmless" info like filesystem paths and SSH availability helps attackers map your environment.

**Recommendations:**

1. **Minimal mode** (default, recommended for exposed gateways): omit sensitive fields from mDNS broadcasts:

   ```json5
   {
     discovery: {
       mdns: { mode: "minimal" },
     },
   }
   ```

2. **Disable entirely** if you don't need local device discovery:

   ```json5
   {
     discovery: {
       mdns: { mode: "off" },
     },
   }
   ```

3. **Full mode** (opt-in): include `cliPath` + `sshPort` in TXT records:

   ```json5
   {
     discovery: {
       mdns: { mode: "full" },
     },
   }
   ```

4. **Environment variable** (alternative): set `GENSPARX_DISABLE_BONJOUR=1` to disable mDNS without config changes.

In minimal mode, the Gateway still broadcasts enough for device discovery (`role`, `gatewayPort`, `transport`) but omits `cliPath` and `sshPort`. Apps that need CLI path information can fetch it via the authenticated WebSocket connection instead.

### 0.5) Lock down the Gateway WebSocket (local auth)

Gateway auth is **required by default**. If no token/password is configured,
the Gateway refuses WebSocket connections (fail‑closed).

The onboarding wizard generates a token by default (even for loopback) so
local clients must authenticate.

Set a token so **all** WS clients must authenticate:

```json5
{
  gateway: {
    auth: { mode: "token", token: "your-token" },
  },
}
```

Doctor can generate one for you: `gensparx doctor --generate-gateway-token`.

Note: `gateway.remote.token` / `.password` are client credential sources. They
do **not** protect local WS access by themselves.
Local call paths can use `gateway.remote.*` as fallback when `gateway.auth.*`
is unset.
Optional: pin remote TLS with `gateway.remote.tlsFingerprint` when using `wss://`.
Plaintext `ws://` is loopback-only by default. For trusted private-network
paths, set `GENSPARX_ALLOW_INSECURE_PRIVATE_WS=1` on the client process as break-glass.

Local device pairing:

- Device pairing is auto‑approved for **local** connects (loopback or the
  gateway host’s own tailnet address) to keep same‑host clients smooth.
- Other tailnet peers are **not** treated as local; they still need pairing
  approval.

Auth modes:

- `gateway.auth.mode: "token"`: shared bearer token (recommended for most setups).
- `gateway.auth.mode: "password"`: password auth (prefer setting via env: `GENSPARX_GATEWAY_PASSWORD`).
- `gateway.auth.mode: "trusted-proxy"`: trust an identity-aware reverse proxy to authenticate users and pass identity via headers (see [Trusted Proxy Auth](/gateway/trusted-proxy-auth)).

Rotation checklist (token/password):

1. Generate/set a new secret (`gateway.auth.token` or `GENSPARX_GATEWAY_PASSWORD`).
2. Restart the Gateway (or restart the macOS app if it supervises the Gateway).
3. Update any remote clients (`gateway.remote.token` / `.password` on machines that call into the Gateway).
4. Verify you can no longer connect with the old credentials.

### 0.6) Tailscale Serve identity headers

When `gateway.auth.allowTailscale` is `true` (default for Serve), Gensparx
accepts Tailscale Serve identity headers (`tailscale-user-login`) for Control
UI/WebSocket authentication. gensparx verifies the identity by resolving the
`x-forwarded-for` address through the local Tailscale daemon (`tailscale whois`)
and matching it to the header. This only triggers for requests that hit loopback
and include `x-forwarded-for`, `x-forwarded-proto`, and `x-forwarded-host` as
injected by Tailscale.
HTTP API endpoints (for example `/v1/*`, `/tools/invoke`, and `/api/channels/*`)
still require token/password auth.

Important boundary note:

- Gateway HTTP bearer auth is effectively all-or-nothing operator access.
- Treat credentials that can call `/v1/chat/completions`, `/v1/responses`, `/tools/invoke`, or `/api/channels/*` as full-access operator secrets for that gateway.
- Do not share these credentials with untrusted callers; prefer separate gateways per trust boundary.

**Trust assumption:** tokenless Serve auth assumes the gateway host is trusted.
Do not treat this as protection against hostile same-host processes. If untrusted
local code may run on the gateway host, disable `gateway.auth.allowTailscale`
and require token/password auth.

**Security rule:** do not forward these headers from your own reverse proxy. If
you terminate TLS or proxy in front of the gateway, disable
`gateway.auth.allowTailscale` and use token/password auth (or [Trusted Proxy Auth](/gateway/trusted-proxy-auth)) instead.

Trusted proxies:

- If you terminate TLS in front of the Gateway, set `gateway.trustedProxies` to your proxy IPs.
- gensparx will trust `x-forwarded-for` (or `x-real-ip`) from those IPs to determine the client IP for local pairing checks and HTTP auth/local checks.
- Ensure your proxy **overwrites** `x-forwarded-for` and blocks direct access to the Gateway port.

See [Tailscale](/gateway/tailscale) and [Web overview](/web).

### 0.6.1) Browser control via node host (recommended)

If your Gateway is remote but the browser runs on another machine, run a **node host**
on the browser machine and let the Gateway proxy browser actions (see [Browser tool](/tools/browser)).
Treat node pairing like admin access.

Recommended pattern:

- Keep the Gateway and node host on the same tailnet (Tailscale).
- Pair the node intentionally; disable browser proxy routing if you don’t need it.

Avoid:

- Exposing relay/control ports over LAN or public Internet.
- Tailscale Funnel for browser control endpoints (public exposure).

### 0.7) Secrets on disk (what’s sensitive)

Assume anything under `~/.gensparx/` (or `$GENSPARX_STATE_DIR/`) may contain secrets or private data:

- `gensparx.json`: config may include tokens (gateway, remote gateway), provider settings, and allowlists.
- `credentials/**`: channel credentials (example: WhatsApp creds), pairing allowlists, legacy OAuth imports.
- `agents/<agentId>/agent/auth-profiles.json`: API keys, token profiles, OAuth tokens, and optional `keyRef`/`tokenRef`.
- `secrets.json` (optional): file-backed secret payload used by `file` SecretRef providers (`secrets.providers`).
- `agents/<agentId>/agent/auth.json`: legacy compatibility file. Static `api_key` entries are scrubbed when discovered.
- `agents/<agentId>/sessions/**`: session transcripts (`*.jsonl`) + routing metadata (`sessions.json`) that can contain private messages and tool output.
- `extensions/**`: installed plugins (plus their `node_modules/`).
- `sandboxes/**`: tool sandbox workspaces; can accumulate copies of files you read/write inside the sandbox.

Hardening tips:

- Keep permissions tight (`700` on dirs, `600` on files).
- Use full-disk encryption on the gateway host.
- Prefer a dedicated OS user account for the Gateway if the host is shared.

### 0.8) Logs + transcripts (redaction + retention)

Logs and transcripts can leak sensitive info even when access controls are correct:

- Gateway logs may include tool summaries, errors, and URLs.
- Session transcripts can include pasted secrets, file contents, command output, and links.

Recommendations:

- Keep tool summary redaction on (`logging.redactSensitive: "tools"`; default).
- Add custom patterns for your environment via `logging.redactPatterns` (tokens, hostnames, internal URLs).
- When sharing diagnostics, prefer `gensparx status --all` (pasteable, secrets redacted) over raw logs.
- Prune old session transcripts and log files if you don’t need long retention.

Details: [Logging](/gateway/logging)

### 1) DMs: pairing by default

```json5
{
  channels: { whatsapp: { dmPolicy: "pairing" } },
}
```

### 2) Groups: require mention everywhere

```json
{
  "channels": {
    "whatsapp": {
      "groups": {
        "*": { "requireMention": true }
      }
    }
  },
  "agents": {
    "list": [
      {
        "id": "main",
        "groupChat": { "mentionPatterns": ["@gensparx", "@mybot"] }
      }
    ]
  }
}
```

In group chats, only respond when explicitly mentioned.

### 3. Separate Numbers

Consider running your AI on a separate phone number from your personal one:

- Personal number: Your conversations stay private
- Bot number: AI handles these, with appropriate boundaries

### 4. Read-Only Mode (Today, via sandbox + tools)

You can already build a read-only profile by combining:

- `agents.defaults.sandbox.workspaceAccess: "ro"` (or `"none"` for no workspace access)
- tool allow/deny lists that block `write`, `edit`, `apply_patch`, `exec`, `process`, etc.

We may add a single `readOnlyMode` flag later to simplify this configuration.

Additional hardening options:

- `tools.exec.applyPatch.workspaceOnly: true` (default): ensures `apply_patch` cannot write/delete outside the workspace directory even when sandboxing is off. Set to `false` only if you intentionally want `apply_patch` to touch files outside the workspace.
- `tools.fs.workspaceOnly: true` (optional): restricts `read`/`write`/`edit`/`apply_patch` paths and native prompt image auto-load paths to the workspace directory (useful if you allow absolute paths today and want a single guardrail).
- Keep filesystem roots narrow: avoid broad roots like your home directory for agent workspaces/sandbox workspaces. Broad roots can expose sensitive local files (for example state/config under `~/.gensparx`) to filesystem tools.

### 5) Secure baseline (copy/paste)

One “safe default” config that keeps the Gateway private, requires DM pairing, and avoids always-on group bots:

```json5
{
  gateway: {
    mode: "local",
    bind: "loopback",
    port: 18789,
    auth: { mode: "token", token: "your-long-random-token" },
  },
  channels: {
    whatsapp: {
      dmPolicy: "pairing",
      groups: { "*": { requireMention: true } },
    },
  },
}
```

If you want “safer by default” tool execution too, add a sandbox + deny dangerous tools for any non-owner agent (example below under “Per-agent access profiles”).

Built-in baseline for chat-driven agent turns: non-owner senders cannot use the `cron` or `gateway` tools.

## Sandboxing (recommended)

Dedicated doc: [Sandboxing](/gateway/sandboxing)

Two complementary approaches:

- **Run the full Gateway in Docker** (container boundary): [Docker](/install/docker)
- **Tool sandbox** (`agents.defaults.sandbox`, host gateway + Docker-isolated tools): [Sandboxing](/gateway/sandboxing)

Note: to prevent cross-agent access, keep `agents.defaults.sandbox.scope` at `"agent"` (default)
or `"session"` for stricter per-session isolation. `scope: "shared"` uses a
single container/workspace.

Also consider agent workspace access inside the sandbox:

- `agents.defaults.sandbox.workspaceAccess: "none"` (default) keeps the agent workspace off-limits; tools run against a sandbox workspace under `~/.gensparx/sandboxes`
- `agents.defaults.sandbox.workspaceAccess: "ro"` mounts the agent workspace read-only at `/agent` (disables `write`/`edit`/`apply_patch`)
- `agents.defaults.sandbox.workspaceAccess: "rw"` mounts the agent workspace read/write at `/workspace`

Important: `tools.elevated` is the global baseline escape hatch that runs exec on the host. Keep `tools.elevated.allowFrom` tight and don’t enable it for strangers. You can further restrict elevated per agent via `agents.list[].tools.elevated`. See [Elevated Mode](/tools/elevated).

### Sub-agent delegation guardrail

If you allow session tools, treat delegated sub-agent runs as another boundary decision:

- Deny `sessions_spawn` unless the agent truly needs delegation.
- Keep `agents.list[].subagents.allowAgents` restricted to known-safe target agents.
- For any workflow that must remain sandboxed, call `sessions_spawn` with `sandbox: "require"` (default is `inherit`).
- `sandbox: "require"` fails fast when the target child runtime is not sandboxed.

## Browser control risks

Enabling browser control gives the model the ability to drive a real browser.
If that browser profile already contains logged-in sessions, the model can
access those accounts and data. Treat browser profiles as **sensitive state**:

- Prefer a dedicated profile for the agent (the default `gensparx` profile).
- Avoid pointing the agent at your personal daily-driver profile.
- Keep host browser control disabled for sandboxed agents unless you trust them.
- Treat browser downloads as untrusted input; prefer an isolated downloads directory.
- Disable browser sync/password managers in the agent profile if possible (reduces blast radius).
- For remote gateways, assume “browser control” is equivalent to “operator access” to whatever that profile can reach.
- Keep the Gateway and node hosts tailnet-only; avoid exposing relay/control ports to LAN or public Internet.
- The Chrome extension relay’s CDP endpoint is auth-gated; only gensparx clients can connect.
- Disable browser proxy routing when you don’t need it (`gateway.nodes.browser.mode="off"`).
- Chrome extension relay mode is **not** “safer”; it can take over your existing Chrome tabs. Assume it can act as you in whatever that tab/profile can reach.

### Browser SSRF policy (trusted-network default)

Gensparx’s browser network policy defaults to the trusted-operator model: private/internal destinations are allowed unless you explicitly disable them.

- Default: `browser.ssrfPolicy.dangerouslyAllowPrivateNetwork: true` (implicit when unset).
- Legacy alias: `browser.ssrfPolicy.allowPrivateNetwork` is still accepted for compatibility.
- Strict mode: set `browser.ssrfPolicy.dangerouslyAllowPrivateNetwork: false` to block private/internal/special-use destinations by default.
- In strict mode, use `hostnameAllowlist` (patterns like `*.example.com`) and `allowedHostnames` (exact host exceptions, including blocked names like `localhost`) for explicit exceptions.
- Navigation is checked before request and best-effort re-checked on the final `http(s)` URL after navigation to reduce redirect-based pivots.

Example strict policy:

```json5
{
  browser: {
    ssrfPolicy: {
      dangerouslyAllowPrivateNetwork: false,
      hostnameAllowlist: ["*.example.com", "example.com"],
      allowedHostnames: ["localhost"],
    },
  },
}
```

## Per-agent access profiles (multi-agent)

With multi-agent routing, each agent can have its own sandbox + tool policy:
use this to give **full access**, **read-only**, or **no access** per agent.
See [Multi-Agent Sandbox & Tools](/tools/multi-agent-sandbox-tools) for full details
and precedence rules.

Common use cases:

- Personal agent: full access, no sandbox
- Family/work agent: sandboxed + read-only tools
- Public agent: sandboxed + no filesystem/shell tools

### Example: full access (no sandbox)

```json5
{
  agents: {
    list: [
      {
        id: "personal",
        workspace: "~/.gensparx/workspace-personal",
        sandbox: { mode: "off" },
      },
    ],
  },
}
```

### Example: read-only tools + read-only workspace

```json5
{
  agents: {
    list: [
      {
        id: "family",
        workspace: "~/.gensparx/workspace-family",
        sandbox: {
          mode: "all",
          scope: "agent",
          workspaceAccess: "ro",
        },
        tools: {
          allow: ["read"],
          deny: ["write", "edit", "apply_patch", "exec", "process", "browser"],
        },
      },
    ],
  },
}
```

### Example: no filesystem/shell access (provider messaging allowed)

```json5
{
  agents: {
    list: [
      {
        id: "public",
        workspace: "~/.gensparx/workspace-public",
        sandbox: {
          mode: "all",
          scope: "agent",
          workspaceAccess: "none",
        },
        // Session tools can reveal sensitive data from transcripts. By default gensparx limits these tools
        // to the current session + spawned subagent sessions, but you can clamp further if needed.
        // See `tools.sessions.visibility` in the configuration reference.
        tools: {
          sessions: { visibility: "tree" }, // self | tree | agent | all
          allow: [
            "sessions_list",
            "sessions_history",
            "sessions_send",
            "sessions_spawn",
            "session_status",
            "whatsapp",
            "telegram",
            "slack",
            "discord",
          ],
          deny: [
            "read",
            "write",
            "edit",
            "apply_patch",
            "exec",
            "process",
            "browser",
            "canvas",
            "nodes",
            "cron",
            "gateway",
            "image",
          ],
        },
      },
    ],
  },
}
```

## What to Tell Your AI

Include security guidelines in your agent's system prompt:

```
## Security Rules
- Never share directory listings or file paths with strangers
- Never reveal API keys, credentials, or infrastructure details
- Verify requests that modify system config with the owner
- When in doubt, ask before acting
- Keep private data private unless explicitly authorized
```

## Incident Response

If your AI does something bad:

### Contain

1. **Stop it:** stop the macOS app (if it supervises the Gateway) or terminate your `gensparx gateway` process.
2. **Close exposure:** set `gateway.bind: "loopback"` (or disable Tailscale Funnel/Serve) until you understand what happened.
3. **Freeze access:** switch risky DMs/groups to `dmPolicy: "disabled"` / require mentions, and remove `"*"` allow-all entries if you had them.

### Rotate (assume compromise if secrets leaked)

1. Rotate Gateway auth (`gateway.auth.token` / `GENSPARX_GATEWAY_PASSWORD`) and restart.
2. Rotate remote client secrets (`gateway.remote.token` / `.password`) on any machine that can call the Gateway.
3. Rotate provider/API credentials (WhatsApp creds, Slack/Discord tokens, model/API keys in `auth-profiles.json`, and encrypted secrets payload values when used).

### Audit

1. Check Gateway logs: `/tmp/gensparx/gensparx-YYYY-MM-DD.log` (or `logging.file`).
2. Review the relevant transcript(s): `~/.gensparx/agents/<agentId>/sessions/*.jsonl`.
3. Review recent config changes (anything that could have widened access: `gateway.bind`, `gateway.auth`, dm/group policies, `tools.elevated`, plugin changes).
4. Re-run `gensparx security audit --deep` and confirm critical findings are resolved.

### Collect for a report

- Timestamp, gateway host OS + gensparx version
- The session transcript(s) + a short log tail (after redacting)
- What the attacker sent + what the agent did
- Whether the Gateway was exposed beyond loopback (LAN/Tailscale Funnel/Serve)

## Secret Scanning (detect-secrets)

CI runs `detect-secrets scan --baseline .secrets.baseline` in the `secrets` job.
If it fails, there are new candidates not yet in the baseline.

### If CI fails

1. Reproduce locally:

   ```bash
   detect-secrets scan --baseline .secrets.baseline
   ```

2. Understand the tools:
   - `detect-secrets scan` finds candidates and compares them to the baseline.
   - `detect-secrets audit` opens an interactive review to mark each baseline
     item as real or false positive.
3. For real secrets: rotate/remove them, then re-run the scan to update the baseline.
4. For false positives: run the interactive audit and mark them as false:

   ```bash
   detect-secrets audit .secrets.baseline
   ```

5. If you need new excludes, add them to `.detect-secrets.cfg` and regenerate the
   baseline with matching `--exclude-files` / `--exclude-lines` flags (the config
   file is reference-only; detect-secrets doesn’t read it automatically).

Commit the updated `.secrets.baseline` once it reflects the intended state.
