DO NOT open public issues for security vulnerabilities.

1. Email: Send security reports to security@universal-connector.org (if available) or create a private security advisory on GitHub
2. Include:
   • Description of the vulnerability
   • Steps to reproduce
   • Potential impact
   • Suggested fix (if any)
3. Response Time: We aim to respond within 48 hours
4. Disclosure: Coordinated disclosure after patch is available (typically 90 days)

In Scope:

• LSP server vulnerabilities (command injection, memory safety)
• HTTP API vulnerabilities (authentication bypass, injection attacks)
• WebSocket vulnerabilities (message injection, DoS)
• Dependency vulnerabilities
• Build process security issues

Out of Scope:

• Editor client vulnerabilities (responsibility of editor maintainers)
• Denial of service requiring unrealistic resources
• Social engineering attacks

1. Memory Safety: Rust's ownership system prevents:

   • Buffer overflows
   • Use-after-free
   • Data races
   • Null pointer dereferences

2. Input Validation:

   • All HTTP inputs validated
   • LSP messages validated against protocol
   • Document size limits enforced
   • Format validation for conversions

3. Dependency Management:

   • Regular cargo audit runs
   • Minimal dependency surface
   • Pinned versions in Cargo.lock

4. Build Security:

   • Reproducible builds via Cargo
   • No unsafe code blocks
   • Strict compiler warnings

1. No Authentication: Server currently has no authentication mechanism

   • Mitigation: Deploy behind reverse proxy with auth
   • Status: Planned for v0.2.0

2. No Rate Limiting: APIs not rate-limited

   • Mitigation: Use reverse proxy rate limiting
   • Status: Planned for v0.2.0

3. No TLS: Server doesn't implement TLS

   • Mitigation: Use reverse proxy (nginx, Apache)
   • Status: Recommended deployment pattern

4. Document Storage: In-memory only, no persistence

   • Impact: DoS via memory exhaustion possible
   • Mitigation: Resource limits at OS/container level
   • Status: Acceptable for current use case
