We take the security of the MCP Rust Examples project seriously. If you discover a security vulnerability, please report it responsibly.

For security issues, please do NOT create a public GitHub issue.

Instead, please report security vulnerabilities through one of these channels:

1. GitHub Security Advisories (Preferred)

   • Go to the Security tab of this repository
   • Click "Report a vulnerability"
   • Fill out the private security advisory form

2. Email

   • Send details to: security@remolab.ai
   • Include "MCP-SECURITY" in the subject line
   • Provide detailed information about the vulnerability

3. Encrypted Communication

   • For highly sensitive issues, request our PGP key
   • Contact: hamze@remolab.ai

We are committed to responding to security reports promptly:

• Initial Response: Within 48 hours
• Confirmation: Within 72 hours
• Status Updates: Every 7 days until resolution
• Fix Development: Depends on complexity and severity
• Public Disclosure: After fix is released (coordinated disclosure)

We provide security updates for the following versions:

Educational Examples:

• Examples are maintained for educational purposes
• Security fixes applied to patterns and practices
• Dependencies updated regularly for known vulnerabilities

Dependencies:

• Regular security audits using cargo audit
• Automated dependency updates via Dependabot
• Manual review of security advisories

Code Issues:

• Unsafe Rust usage patterns
• Memory safety violations
• Cryptographic implementation flaws
• Authentication/authorization bypasses
• Input validation failures
• SQL injection possibilities
• Path traversal vulnerabilities
• Denial of service vectors

Dependency Issues:

• Known vulnerabilities in dependencies
• Outdated packages with security patches
• License compliance issues
• Supply chain security concerns

Documentation Issues:

• Misleading security guidance
• Dangerous code examples
• Missing security warnings

Educational Context:

• Intentionally simplified examples for learning
• Missing production hardening in tutorials
• Performance optimizations over security (when documented)

Infrastructure:

• GitHub Actions workflow security (report to GitHub)
• Third-party service vulnerabilities
• Network infrastructure issues

Continuous Monitoring:

• Dependabot: Automated dependency updates
• GitHub Security Advisories: Real-time vulnerability alerts
• Cargo Audit: Weekly security scans
• CodeQL Analysis: Static security analysis
• OSSF Scorecard: Supply chain security metrics

CI/CD Security:

• Dependency review on pull requests
• Security-focused Clippy lints
• License compliance checks
• Vulnerability scanning in workflows

Code Review Process:

• Security-focused code reviews
• Threat modeling for complex examples
• Regular security architecture reviews
• External security consultations

Documentation Review:

• Security guidance verification
• Best practices validation
• Threat model documentation
• Security training materials

This project contains educational examples that prioritize learning over production security:

⚠️ Important Disclaimers:

1. Simplified Authentication: Examples use basic authentication for clarity
2. Error Handling: Some examples use .unwrap() for brevity (not production-ready)
3. Input Validation: Basic validation for demonstration purposes
4. Cryptography: Examples use simple hashing (real applications should use bcrypt/Argon2)
5. Network Security: Examples don't include full TLS configuration

Dependency Vulnerabilities:

• RUSTSEC-2023-0071: RSA timing sidechannel in rsa crate
  • Impact: Low (transitive dependency through sqlx-mysql)
  • Mitigation: Educational examples don't perform sensitive RSA operations
  • Status: Monitoring for upstream fix

Unmaintained Dependencies:

• RUSTSEC-2024-0436: paste crate no longer maintained
  • Impact: Low (macro-only, build-time dependency)
  • Mitigation: Evaluating alternatives
  • Status: Non-critical for educational use

Code Security:

// ✅ Good: Proper error handling
match operation() {
    Ok(result) => handle_success(result),
    Err(error) => handle_error(error),
}

// ❌ Avoid in production: Panic on errors
let result = operation().unwrap();

Input Validation:

// ✅ Good: Validate all inputs
fn process_data(input: &str) -> Result<String, ValidationError> {
    if input.is_empty() {
        return Err(ValidationError::EmptyInput);
    }
    // Process validated input
}

Secure Defaults:

// ✅ Good: Secure by default
pub struct Config {
    pub enable_debug: bool,        // Default: false
    pub max_connections: usize,    // Default: reasonable limit
    pub timeout_seconds: u64,      // Default: reasonable timeout
}

impl Default for Config {
    fn default() -> Self {
        Self {
            enable_debug: false,        // Secure default
            max_connections: 100,       // Reasonable limit
            timeout_seconds: 30,        // Prevent hanging
        }
    }
}

Production Deployment:

1. Review Examples: Understand security limitations
2. Add Proper Authentication: Implement robust auth systems
3. Input Validation: Add comprehensive validation
4. Error Handling: Replace .unwrap() with proper error handling
5. Monitoring: Implement security monitoring and logging
6. Regular Updates: Keep dependencies updated
7. Security Testing: Perform security testing before production
