Reporting a Vulnerability

DO NOT open public issues for security vulnerabilities.

Reporting Process

  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)

Security Scope

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

Security Measures

Current Protections

  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

Known Limitations

  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

Security Best Practices

Deployment

# Run as non-root user
useradd -r -s /bin/false connector
sudo -u connector ./universal-connector-server

# Use firewall rules
ufw allow from trusted_ip to any port 8080
ufw deny 8080

# Container security
docker run --read-only --cap-drop=ALL --security-opt=no-new-privileges \
  --memory=100m --cpus=1.0 universal-connector

Configuration

# Disable unused features
export ENABLE_LSP=true
export ENABLE_HTTP=false  # If not needed
export ENABLE_WS=false    # If not needed

# Bind to localhost only
export HTTP_ADDR=127.0.0.1:8080
export WS_ADDR=127.0.0.1:8081

Security Roadmap

  • ❏ v0.2.0: Add JWT-based authentication

  • ❏ v0.2.0: Implement rate limiting

  • ❏ v0.3.0: Add TLS support

  • ❏ v0.3.0: Implement document size limits

  • ❏ v0.4.0: Add audit logging

  • ❏ v0.4.0: Implement RBAC (Role-Based Access Control)
