This commit addresses multiple high-priority security and reliability issues
found during comprehensive codebase analysis:
1. CRITICAL: Remove hardcoded TURN server credentials
- Removed dangerous default secret 'default-secret-change-me'
- Now throws error if TURN_SECRET env var not set
- Also requires TURN_SERVER_HOST and TURN_SERVER_PORT to be configured
- Prevents attackers from generating valid TURN credentials
- File: src/backend/services/callService.js
2. HIGH: Add array bounds checking before accessing database results
- Added validation before accessing rows[0] in multiple locations
- Prevents "Cannot read property of undefined" runtime crashes
- Provides clear error messages when records not found
- Files affected:
- src/backend/services/callService.js (conversation lookup)
- src/backend/services/messagingService.js (user lookup)
- src/backend/services/gameforgeIntegration.js (integration & conversation creation)
3. HIGH: Secure development mode authentication bypass
- Added second security layer requiring ALLOW_DEV_BYPASS='true'
- Prevents accidental auth bypass if NODE_ENV accidentally set to 'development'
- Added warning logs when bypass is active
- File: src/backend/middleware/auth.js
These fixes prevent:
- TURN server abuse via known secrets
- Runtime crashes from missing database records
- Accidental authentication bypass in production environments
Previously, if encryption failed for any recipient, the error was only
logged to console and the code continued, resulting in a message being
sent that some recipients couldn't decrypt. This creates a security and
reliability issue.
Changes:
- Collect all failed encryption attempts instead of silently logging
- Throw an error if any recipient encryption fails
- Provide detailed error message listing number of failures
- Implement all-or-nothing approach to prevent partial message delivery
This ensures senders are notified immediately if message encryption
fails for any recipient, preventing silent security failures.
- Updated all Chat component styles (Chat, MessageInput, MessageList, ConversationList)
- Replaced purple/pink gradients with cyan/green gaming theme
- Implemented glassmorphism effects with backdrop blur
- Updated message bubbles with gradient for own messages, dark glass for others
- Changed all light backgrounds to OLED-friendly pure black
- Added cyan glow effects and shadows throughout
- Installed react-router-dom dependency
- Updated Demo.css with full dark theme
- All components now match Astro landing site aesthetic
- Fixed db module import path from '../db' to '../database/db'
- Applied to gameforgeIntegration.js and gameforgeRoutes.js
- Server now starts successfully with GameForge routes enabled
- Added IMPLEMENTATION-SUMMARY.md with complete Phase 3 overview
