Gremlin MCP Server

# Security Policy ## Supported Versions We actively maintain and provide security updates for the following versions: | Version | Supported | | ------- | --------- | | 1.x.x | ✅ Yes | | < 1.0 | ❌ No | ## Known Security Limitations ### Current Security Status **⚠️ IMPORTANT**: This software is currently in development and has known security limitations. It is **NOT recommended for production use** without additional security measures. ### Identified Vulnerabilities #### 1. Gremlin Query Injection - **Risk Level**: High - **Description**: The `import_graph_data` and `export_subgraph` tools construct Gremlin queries from user input with basic sanitization only - **Impact**: Malicious queries could potentially: - Access unauthorized data - Modify or delete graph data - Cause denial of service - **Mitigation**: Use only in trusted environments with validated input #### 2. Resource Exhaustion - **Risk Level**: Medium - **Description**: No connection pooling, rate limiting, or query timeouts - **Impact**: Server could be overwhelmed by: - Rapid successive requests - Long-running queries - Connection exhaustion - **Mitigation**: Deploy behind a proxy with rate limiting #### 3. Information Disclosure - **Risk Level**: Low-Medium - **Description**: Detailed error messages may expose internal system information - **Impact**: Error responses could reveal: - Database schema details - Internal server structure - Configuration information - **Mitigation**: Configure appropriate log levels in production ## Reporting a Vulnerability ### How to Report If you discover a security vulnerability, please follow these steps: 1. **DO NOT** open a public GitHub issue 2. **DO NOT** disclose the vulnerability publicly until it has been addressed Instead, please report security issues by: **Email**: security@your-domain.com (replace with actual email) **GitHub**: Create a private security advisory via GitHub's Security tab ### What to Include Please provide as much information as possible: - **Description**: Clear description of the vulnerability - **Steps to Reproduce**: Detailed steps to reproduce the issue - **Impact Assessment**: Your assessment of the potential impact - **Proof of Concept**: Code or screenshots demonstrating the issue (if applicable) - **Suggested Fix**: Any suggestions for fixing the vulnerability (optional) ### Response Timeline We aim to respond to security reports according to the following timeline: - **Initial Response**: Within 48 hours - **Vulnerability Assessment**: Within 1 week - **Fix Development**: Within 2-4 weeks (depending on complexity) - **Release and Disclosure**: Within 6 weeks of initial report ### Vulnerability Handling Process 1. **Receipt Confirmation**: We'll confirm receipt of your report within 48 hours 2. **Initial Assessment**: We'll provide an initial assessment within 1 week 3. **Investigation**: Our team will investigate and validate the issue 4. **Fix Development**: We'll develop and test a fix 5. **Coordinated Disclosure**: We'll coordinate with you on timing for public disclosure 6. **Release**: We'll release the fix and publish a security advisory ## Security Best Practices ### For Users When using this software: - **Environment**: Use only in trusted, controlled environments - **Network Security**: Deploy behind firewalls with restricted access - **Authentication**: Use strong credentials for Gremlin server connections - **Monitoring**: Monitor query patterns and resource usage - **Updates**: Keep dependencies and the software updated - **Input Validation**: Validate all user inputs before processing ### For Contributors When contributing code: - **Input Validation**: Always validate and sanitize user inputs - **Error Handling**: Avoid exposing sensitive information in error messages - **Dependencies**: Keep dependencies updated and scan for vulnerabilities - **Code Review**: All security-related changes require thorough review - **Testing**: Include security test cases for new features ## Security Roadmap We are actively working on improving security with these planned enhancements: ### Short Term (Next Release) - [ ] Enhanced query sanitization and validation - [ ] Improved error handling to prevent information disclosure - [ ] Basic rate limiting implementation ### Medium Term (Next 2-3 Releases) - [ ] Connection pooling with proper timeout handling - [ ] Query allowlisting for production environments - [ ] Comprehensive audit logging - [ ] Security-focused configuration options ### Long Term (Future Releases) - [ ] Advanced query analysis and blocking - [ ] Integration with security scanning tools - [ ] Multi-factor authentication support - [ ] End-to-end encryption for sensitive operations ## Security Testing ### Automated Security Checks Our CI/CD pipeline includes: - **Dependency Scanning**: `npm audit` and `audit-ci` for known vulnerabilities - **Static Analysis**: ESLint with security-focused rules - **Type Safety**: TypeScript strict mode for memory safety ### Manual Security Testing We perform regular manual security assessments including: - Query injection testing - Input validation testing - Error handling verification - Access control validation ### Security Tools Integration We use the following tools for security monitoring: - `npm audit` - Dependency vulnerability scanning - `audit-ci` - CI/CD security gate - GitHub Security Advisories - Vulnerability tracking - Dependabot - Automated dependency updates ## Acknowledgments We appreciate security researchers and users who help improve the security of this project. Contributors who report valid security issues will be: - Credited in the security advisory (unless they prefer to remain anonymous) - Listed in our security acknowledgments - Invited to collaborate on security improvements ## Contact For general security questions or concerns: - Create a GitHub Discussion in the Security category - Email: security@your-domain.com (replace with actual email) For urgent security matters: - Follow the vulnerability reporting process above - Contact maintainers directly via GitHub --- **Note**: This security policy is regularly reviewed and updated.
