# Changelog - HaikzBot Security & Feature Update

**Tanggal:** 2026-05-30  
**Status:** ✅ SELESAI

---

## 🔴 CRITICAL BUGS FIXED

### 1. Schema Mismatch `products.category` → `category_id`
**File:** `src/commands/product.js`, `src/commands/store.js`

**Masalah:** Command `/product add` dan `/store panel` crash karena query pakai kolom `category` yang tidak ada di schema (seharusnya `category_id`).

**Fix:**
- ✅ Ganti semua query pakai `category_id` dengan JOIN ke tabel `categories`
- ✅ Auto-create category kalau belum ada saat `/product add`
- ✅ Tambah option `image_url` di command `/product add`

**Contoh:**
```bash
/product add name:"Discord Nitro" price:50000 category:"Discord App" image_url:"https://cdn.discordapp.com/emojis/1096190031948214272.png"
```

---

### 2. SQL Injection di Dashboard API
**File:** `src/web/routes/api.js:182-190`

**Masalah:** Endpoint `/api/stats` vulnerable terhadap SQL injection via parameter `guild_id`.

**Fix:**
- ✅ Ganti string interpolation dengan parameter binding
- ✅ Semua query sekarang pakai prepared statements

**Before:**
```javascript
const filter = guild_id ? `WHERE guild_id = '${guild_id}'` : '';  // ❌ VULNERABLE
```

**After:**
```javascript
db.prepare('SELECT ... WHERE guild_id = ?').get(guild_id);  // ✅ SAFE
```

---

## 🟠 HIGH SECURITY FIXES

### 3. Token Security
**File:** `src/web/server.js`, `.env`

**Fix:**
- ✅ Dashboard token sekarang **wajib** dari `.env` (tidak ada default)
- ✅ Token tidak di-log ke console lagi
- ✅ Generate token baru yang kuat: `622e5783c187f3e3da7ad0da3fc34f9b9b47894925476d7fdf29d75b152a880b`
- ✅ Validasi Tripay credentials saat `PAYMENT_PROVIDER=tripay`

**Action Required:**
```bash
# Regenerate Discord token di Developer Portal kalau .env pernah ter-commit
# Pastikan .env di .gitignore (sudah ada)
```

---

### 4. Clone @everyone Permission Bug
**File:** `src/modules/server-clone/interactions.js`

**Masalah:** Permission overwrite untuk `@everyone` tidak ter-map dengan benar ke guild baru.

**Fix:**
- ✅ Simpan `source_guild_id` di `roleIdMap` untuk mapping `@everyone` yang benar

---

### 5. Stock Race Condition
**File:** `src/modules/payment/delivery.js`

**Masalah:** 2 webhook "PAID" bersamaan bisa allocate stock yang sama ke 2 user berbeda.

**Fix:**
- ✅ Pakai transaction dengan optimistic locking (`UPDATE ... WHERE sold = 0`)
- ✅ Atomic stock allocation

---

## ✨ NEW FEATURES

## 🐛 KNOWN ISSUES (Minor)

1. **Transcript redaction terlalu agresif** - redact semua angka 6-18 digit (termasuk IDs)
2. **No rate limiting** - dashboard API belum ada rate limit (perlu install `express-rate-limit`)
3. **Backup cleanup** - belum ada auto-delete backup lama (keep last 7 days)

**Priority:** LOW - tidak urgent, bisa di-fix nanti.
