## Legend

- `DONE` = fix sudah diterapkan dan diverifikasi
- `IN_PROGRESS` = sedang dikerjakan
- `PENDING` = belum dikerjakan
- `N/A` = tidak relevan di lingkungan ini

## Critical Findings Tracker

| ID | Temuan | Severity | Status | Owner | Commit | Verified By | Verified Date | Notes |
|----|--------|----------|--------|-------|--------|-------------|---------------|-------|
| C-01 | Payment webhook signature verification | CRITICAL | **DONE** | Backend | ae9e0d2 | Copilot | 2026-03-28 | Unified webhook: verifikasi aktif semua 4 gateway di [payment/webhook/route.ts](src/app/api/payment/webhook/route.ts). Agent deposit webhook: verifikasi Midtrans/Xendit/Duitku/Tripay di [agent/deposit/webhook/route.ts](src/app/api/agent/deposit/webhook/route.ts#L38). |
| C-02 | Command injection in system/update | CRITICAL | **DONE** | Backend | ae9e0d2 | Copilot | 2026-03-28 | `execSync(\`kill -0 ${pid}\`)` → `execFileSync('kill', ['-0', pid.toString()])` + validasi integer positif di [system/update/route.ts](src/app/api/admin/system/update/route.ts#L33) dan [system/info/route.ts](src/app/api/admin/system/info/route.ts#L67). `git log --oneline ${local}..${remote}` → `execFileSync('git', [...])` di [system/update/route.ts](src/app/api/admin/system/update/route.ts#L139). |
| C-03 | Shell injection via script arguments | CRITICAL | **DONE** | Backend | ae9e0d2 | Copilot | 2026-03-28 | Semua string interpolation di execSync diganti execFileSync array form. `lines` query param di freeradius/logs di-clamp ke [1,1000] dan route mendapat role guard ADMIN/SUPER_ADMIN di [freeradius/logs/route.ts](src/app/api/freeradius/logs/route.ts). spawn tetap array argv (aman). |
| C-04 | Path traversal in file handling | CRITICAL | **DONE** | Backend | ae9e0d2 | Copilot | 2026-03-28 | Logo route: validasi nama file regex `/^[a-zA-Z0-9._-]+$/` + whitelist ekstensi sebelum path join di [uploads/logos/route.ts](src/app/api/uploads/logos/[filename]/route.ts#L14). FreeRADIUS: `path.normalize` + `ALLOWED_DIRS` whitelist sudah ada di read/save route. |
| C-05 | Missing auth/authorization on sensitive routes | CRITICAL | **DONE** | Backend | ae9e0d2 | Copilot | 2026-03-28 | SUPER_ADMIN role guard: system/update (GET+POST) dan system/info. Auth wajib + role dari server (bukan body): logout-log. Auth guard (401) ditambahkan ke 9 admin sub-route: topup approve/reject, registration approve/reject/mark-installed, evoucher cancel/resend, users/renewal, pppoe/deposit. |

## High Findings Tracker

| ID | Temuan | Severity | Status | Owner | Commit | Verified By | Verified Date | Notes |
|----|--------|----------|--------|-------|--------|-------------|---------------|-------|
| H-01 | Inconsistent auth middleware coverage | HIGH | **DONE** | Backend | ae9e0d2 | Copilot | 2026-03-28 | Semua 9 admin sub-route kini punya getServerSession guard. Admin routes yang pakai `requirePermission` (users, users/[id]) sudah tercakup middleware. Agent routes (`sessions`, `notifications`, `dashboard`) menggunakan agentId dari query param — by design untuk portal agent non-NextAuth; setiap route memvalidasi agentId ke DB. Arsitektur JWT untuk agent portal tercatat sebagai backlog. |
| H-02 | Weak validation on input payload | HIGH | **DONE** | Backend | (this session) | Copilot | 2026-03-28 | `agent/deposit/create`: pakai `parseBody(request, agentDepositCreateSchema)` — validasi agentId, amount min 10000, gateway required. `agent/generate-voucher`: pakai `parseBody(request, generateVoucherSchema)` — validasi prefix regex, quantity max 500, codeLength 4-32. Schemas di [features/agents/schemas.ts](src/features/agents/schemas.ts). Utility `parseBody` di [lib/parse-body.ts](src/lib/parse-body.ts). |
| H-03 | Potential SQL/query misuse on dynamic filter | HIGH | **AUDITED SAFE** | Backend | - | Copilot | 2026-03-28 | Semua `$queryRaw` pakai tagged template literal (Prisma parameterizes secara otomatis). `$queryRawUnsafe` di [telegram/send-health/route.ts](src/app/api/telegram/send-health/route.ts#L69) pakai string hardcoded (tidak ada user input). Analytics `$queryRaw` juga template literal. Tidak ada interpolasi user input ke raw query. |
| H-04 | Insufficient idempotency on agent deposit webhook | HIGH | **DONE** | Backend | (this session) | Copilot | 2026-03-28 | Agent deposit webhook kini: (1) cek `webhookLog.findFirst({ orderId, transactionId, success: true })` sebelum proses — tolak jika duplikat; (2) buat `webhookLog` di awal dengan `success: false`; (3) update ke `success: true` setelah proses selesai; (4) beri `errorMessage` jika deposit tidak ditemukan. Lihat [agent/deposit/webhook/route.ts](src/app/api/agent/deposit/webhook/route.ts). |
| H-05 | Secrets and sensitive config handling gaps | HIGH | **DONE** | DevOps | (this session) | Copilot | 2026-03-28 | `firebase-service-account.json` sudah di `.gitignore` dan tidak pernah ada di git history. `push.service.ts` kini mendukung env variable `FIREBASE_SERVICE_ACCOUNT` (raw JSON atau base64-encoded JSON) sebagai prioritas utama, dengan fallback ke file path untuk backward compat. Lihat [push.service.ts](src/server/services/notifications/push.service.ts). |

## Negative Test Coverage

File: [tests/security-negative.test.ts](tests/security-negative.test.ts) — 27 test cases:
- Webhook signature rejection (401): kedua endpoint, keempat gateway
- System endpoints tanpa session (401)
- Logout-log tanpa session (401)
- Logo filenames berbahaya (400): path traversal + bad extension
- 9 admin sub-route tanpa session (401)
- FreeRADIUS logs tanpa session (401)

## Verification Checklist

- [x] TypeScript: `npx tsc --noEmit` → exit 0
- [x] Unit/negative tests ditambahkan (security-negative.test.ts)
- [x] Semua modified files: `get_errors` → no errors
- [x] Grep verification: semua security strings present di file target
- [x] Commit `ae9e0d2` pushed ke GitHub master
