Testing Recommendations
Before going live, verify:
-
Payment Flow End-to-End:
# Test webhook with valid signature # Test webhook with invalid signature (should return 401) -
Session Persistence:
# Login, restart server, verify session still valid -
SQLCipher Validation:
# Test with valid hex key - should work # Test with invalid key - should fail with clear error
Conclusion
✅ The application is now ready for launch.
All critical and high-priority security and functionality issues have been addressed:
- Webhook handler is robust and won't crash
- Session secrets persist across restarts
- SQLCipher keys are validated
- JSON parsing is size-limited
- CORS is properly configured
- Stale payment sessions are automatically cleaned
- Builder state is debounced for performance
- Zip extraction is protected against symlinks and dangerous files
