## 🔥 Critical Fixes (11)
|
|
|
|
### Backend
|
|
|
|
1. ✅ **Database session leaks** - All endpoints now properly close connections
|
|
2. ✅ **Missing error handling** - Try-finally blocks added throughout
|
|
3. ✅ **Input validation missing** - Length limits and sanitization added
|
|
4. ✅ **File upload vulnerability** - Size limits and path traversal protection
|
|
|
|
### Security
|
|
|
|
5. ✅ **No security headers** - HSTS, XSS protection, frame denial added
|
|
6. ✅ **Unlimited request size** - 16MB limit enforced
|
|
7. ✅ **Insecure sessions** - Secure flags, HTTPOnly, SameSite set
|
|
8. ✅ **Default password risk** - Production validation added
|
|
|
|
### Database
|
|
|
|
9. ✅ **Missing indexes** - 10 indexes added for performance
|
|
10. ✅ **No unique constraints** - Duplicate prevention implemented
|
|
11. ✅ **Orphaned records** - CASCADE deletes configured
|
|

## ⚠️ Action Required
|
|
|
|
### Before Production Deploy
|
|
|
|
1. **Update Environment Variables**
|
|
|
|
```bash
|
|
cp .env.example .env
|
|
# Edit .env with secure values
|
|
python -c "import secrets; print(secrets.token_hex(32))" # Generate SECRET_KEY
|
|
```
|
|
|
|
2. **Backup Database**
|
|
|
|
```bash
|
|
pg_dump church_songlyric > backup_$(date +%Y%m%d).sql
|
|
```
|
|
|
|
3. **Run Migration**
|
|
|
|
```bash
|
|
cd backend
|
|
python migrate_database.py
|
|
```
|
|
|
|
4. **Test Endpoints**
|
|
|
|
```bash
|
|
curl http://localhost:8080/api/health
|
|
```
|
|
|
|
5. **Enable HTTPS** (Critical for production)
|
|

## 🎯 Remaining Recommendations
|
|
|
|
### High Priority
|
|
|
|
- ⚠️ Implement JWT authentication (current: client-side hash)
|
|
- ⚠️ Add rate limiting (prevent brute force)
|
|
- ⚠️ Configure HTTPS/TLS
|
|
- ⚠️ Split large App.js file (7579 lines)
|
|
|
|
### Medium Priority
|
|
|
|
- Add automated tests
|
|
- Implement logging (structured JSON)
|
|
- Add API versioning (/api/v1/)
|
|
- Set up monitoring (Sentry)
|
|
|
|
### Low Priority
|
|
|
|
- Add Redis caching
|
|
- Implement pagination
|
|
- Add performance monitoring
|
|
