🔧 CURRENT ISSUE — CORS Configuration Clarification

Two Deployment Methods

The project supports two distinct deployment approaches:

1. Docker Compose (Production / Containerized)

• Uses docker-compose.yml with Caddy reverse proxy
• Backend container on internal port 8000 → exposed via Caddy on 3002
• Frontend container on internal port 3000 → exposed via Caddy on 3003
• Configuration: ALLOWED_ORIGINS environment variable in docker-compose.yml
• Current setting: http://localhost:3000,http://localhost:3002
• For remote deployment: Must update ALLOWED_ORIGINS to include actual domain (e.g., https://192.168.84.140:3003)

2. start_server.sh (Development / Native)

• Runs Backend (uvicorn) + Frontend (Next.js) + local-ssl-proxy directly
• Backend on port 8000 → SSL proxy on 3002
• Frontend on port 3001 → SSL proxy on 3003
• Issue Fixed: Script now automatically detects local IP and exports ALLOWED_ORIGINS
• Auto-configured for: localhost + detected IP address on both HTTP and HTTPS

Fix Applied (Commit Pending)

Updated start_server.sh to:

1. Detect local IP address (en0/en1 interface)
2. Export ALLOWED_ORIGINS with all applicable origins:
   • HTTP localhost on dev ports (3000/3001)
   • HTTPS localhost on proxy ports (3002/3003)
   • HTTPS on detected IP address on proxy ports
3. Display CORS configuration when starting backend
4. Export JWT_SECRET_KEY if not already set

Result: Frontend at https://<LOCAL_IP>:3003 can now access backend at https://<LOCAL_IP>:3002 without CORS blocks.

English Language Compliance

Fixed Romanian comments in docker-compose.yml:

• "personalizează pentru producție" → "customize for production"
• "GENEREAZĂ O VALOARE SIGURĂ" → "GENERATE A SECURE VALUE"

📋 Complete Implementations

Backend

JWT Authentication [C-01]

• ✅ backend/auth.py — JWT creation, validation, role checking
• ✅ /users/login — returns TokenResponse (access_token, user_id, role, 8h expiry)
• ✅ All routers — Depends(get_current_user) enforcement
• ✅ Admin-only endpoints — Depends(get_current_admin)
• ✅ user_id — extracted from JWT token, NOT from request body [M-02]

Rate Limiting [H-02]

• ✅ slowapi integrated in requirements.txt
• ✅ /items/extract-label — @limiter.limit("10/minute") per IP
• ✅ Protection against spam on AI endpoint

CORS Configuration [M-01]

• ✅ ALLOWED_ORIGINS from environment variable (fallback: localhost:3000, localhost:3002)
• ✅ Specific HTTP methods: GET, POST, PUT, DELETE, OPTIONS
• ✅ allow_credentials=True (valid with specific origins)

Direct Patches

• ✅ C-02 — Removed passwordless bypass
• ✅ C-03 — Admin seed with random password
• ✅ H-01 — LDAP injection fix (escape_filter_chars)
• ✅ H-03 — MIME validation + 10MB upload limit
• ✅ M-03 — LDAP logging via log.debug()

Frontend

JWT Handling [L-01]

• ✅ frontend/lib/auth.ts — saveToken, getToken, getAuthHeader, clearAuth
• ✅ Token storage — localStorage (inventory_token + inventory_user)
• ✅ Login page — saves TokenResponse from /users/login
• ✅ Token attachment — Axios interceptor adds Authorization: Bearer <token> to all requests

Token Expiry [L-01]

• ✅ 401 Unauthorized → clearAuth() + redirect /login
• ✅ Interceptor on axiosInstance
• ✅ Auto-logout on expiration

Deployment

docker-compose.yml

• ✅ Backend environment variables: DATA_DIR, LOGS_DIR, ALLOWED_ORIGINS, JWT_SECRET_KEY
• ✅ Comments for production configuration
• ✅ Fallback values for development

Environment Variables

Variable	Dev Default	Production Required	Purpose
ALLOWED_ORIGINS	localhost:3000, localhost:3002	SET REQUIRED	CORS allowed origins
JWT_SECRET_KEY	ephemeral (random)	SET REQUIRED	JWT signing key
DATA_DIR	/app/data	-	SQLite database location
LOGS_DIR	/app/logs	-	Application logs location

🚀 Production Deployment Checklist

CRITICAL — Set these environment variables before deploy:

• JWT_SECRET_KEY — Generate with openssl rand -hex 32 (store in secrets manager)
• ALLOWED_ORIGINS — Set to actual production domain(s), e.g., https://inventory.example.com
• TLS/HTTPS — Caddy proxy configured with valid SSL certificate
• Database backup — SQLite data/ mapped to persistent volume
• Logs rotation — logs/ mapped and monitored

RECOMMENDED:

• Set log level to WARNING (not DEBUG)
• Configure rate limiting at reverse proxy level (nginx/Cloudflare) for DDoS protection
• Monitor alert on 401 spikes (token expiry issues)
• Periodic JWT_SECRET_KEY rotation (quarterly minimum)

🧪 Local Testing

1. Start Development Stack

docker-compose up --build

2. Test Login

curl -X POST http://localhost:8000/users/login \
  -H "Content-Type: application/json" \
  -d '{"username": "Admin", "password": "<initial_password_from_logs>"}'

3. Test Protected Endpoint with Token

curl -H "Authorization: Bearer <access_token>" \
  http://localhost:8000/items/

4. Test 401 Unauthorized (invalid token)

curl -H "Authorization: Bearer invalid_token" \
  http://localhost:8000/items/
# Expected: 401 Unauthorized

5. Test Rate Limiting (extract-label endpoint)

# 11 requests rapid fire — 11th should fail with 429
for i in {1..15}; do
  curl -X POST -F "file=@image.jpg" \
    -H "Authorization: Bearer <token>" \
    http://localhost:8000/items/extract-label
  sleep 0.1
done

✅ Validations Completed

• ✅ Backend fully secured with JWT
• ✅ Frontend token handling complete
• ✅ Rate limiting on AI endpoint
• ✅ CORS configurable via environment
• ✅ All routers have authentication enforcement
• ✅ Token expiry with automatic login redirect
• ✅ Admin role checks functional
• ✅ LDAP injection protection
• ✅ File upload validation
• ✅ Audit logging with user_id from token

---

🎓 Key Learnings

1. CORS with credentials=True — requires specific origins, NOT wildcards
2. Rate limiting — essential on expensive endpoints (AI processing)
3. JWT expiration — 8h balances security vs. UX
4. user_id from token — eliminates operation spoofing
5. Debug logging — careful with PII leaks (LDAP DNs)

📝 Production Environment Variables Example

# Set these before `docker-compose up`
export JWT_SECRET_KEY="$(openssl rand -hex 32)"
export ALLOWED_ORIGINS="https://inventory.example.com,https://api.example.com"

docker-compose up -d

Or in .env.production (NOT in git):

JWT_SECRET_KEY=abcdef1234567890...
ALLOWED_ORIGINS=https://inventory.example.com
