This project has been analyzed for security vulnerabilities using CodeQL.

• Location: public/peerpigeon-browser.js:145
• Type: js/biased-cryptographic-random
• Severity: Low
• Status: False Positive
• Description: The alert flags string concatenation in the PeerPigeon vendor library as potentially biased cryptographic operations. Upon inspection, this is string concatenation (hex[hi] + hex[hi + 1]) for hex string building, not arithmetic on random numbers.
• Action: No action required. This is vendor code from the official PeerPigeon npm package and the alert is a false positive.

All code written for this project (in src/ directory) has been scanned and contains no security vulnerabilities.

1. Dependency Management: Using official npm packages from trusted sources
2. Input Validation: Player movement and positions are validated before processing
3. Network Security: Using WebRTC for encrypted P2P communication
4. No Sensitive Data: No authentication tokens or sensitive data stored in client code
5. Collision Detection: Prevents players from entering invalid world states

• peerpigeon (v1.1.3): Official WebRTC P2P library with built-in encryption
• pigeonmatch (v1.0.3): Official matchmaking library from same vendor
• vite (v7.3.0): Development dependency for bundling

All dependencies are from npm and regularly maintained.

The game uses:

• WebRTC for encrypted peer-to-peer connections
• Signaling server connection over WSS (WebSocket Secure)
• No central server stores game state or player data
• All game state is client-side or distributed across peers

For production deployment:

1. Enable HTTPS for the web server
2. Configure Content Security Policy headers
3. Consider adding rate limiting for signaling server connections
4. Monitor for updates to dependencies
