Codex Bridge

# Security Policy ## Supported Versions We provide security updates for the following versions of Codex Bridge: | Version | Supported | | ------- | ------------------ | | 1.0.x | :white_check_mark: | ## Reporting a Vulnerability We take security vulnerabilities seriously. If you discover a security vulnerability, please report it responsibly. ### How to Report **Please DO NOT report security vulnerabilities through public GitHub issues.** Instead, please report them by: 1. **Email**: Send details to the maintainer via GitHub (preferred) 2. **GitHub Security**: Use GitHub's private vulnerability reporting feature 3. **Direct Contact**: Create a private issue if the above options aren't available ### What to Include When reporting a vulnerability, please provide: - **Description**: Clear description of the vulnerability - **Impact**: What could an attacker accomplish? - **Reproduction**: Step-by-step instructions to reproduce the issue - **Environment**: Python version, OS, Codex CLI version - **Suggested Fix**: If you have ideas for a solution ### Example Report Template ``` **Vulnerability Type**: [e.g., Code Injection, Information Disclosure] **Severity**: [Low/Medium/High/Critical] **Affected Component**: [e.g., consult_codex function, file handling] **Description**: [Detailed description of the vulnerability] **Steps to Reproduce**: 1. [Step one] 2. [Step two] 3. [Step three] **Impact**: [What could happen if this is exploited] **Environment**: - OS: [e.g., macOS 14.0] - Python: [e.g., 3.11.5] - Codex CLI: [e.g., 1.2.3] - Codex Bridge: [e.g., 1.0.0] ``` ## Response Timeline We aim to respond to security reports according to this timeline: - **Acknowledgment**: Within 48 hours of report - **Initial Assessment**: Within 1 week - **Status Update**: Weekly updates on progress - **Resolution**: Depends on severity and complexity ### Severity Levels - **Critical**: Immediate threat, affects all users - **High**: Significant threat, affects many users - **Medium**: Moderate threat, limited impact - **Low**: Minor threat, minimal impact ## Security Best Practices ### For Users When using Codex Bridge: 1. **Keep Updated**: Always use the latest version 2. **Secure Authentication**: Protect your Codex CLI authentication 3. **File Permissions**: Be careful with file paths and permissions 4. **Network Security**: Use secure networks when possible 5. **Input Validation**: Be cautious with untrusted input in queries ### For Developers When contributing to Codex Bridge: 1. **Input Sanitization**: Always validate and sanitize user input 2. **Path Traversal**: Prevent directory traversal attacks 3. **Command Injection**: Avoid shell injection vulnerabilities 4. **Error Information**: Don't leak sensitive info in error messages 5. **Dependencies**: Keep dependencies updated and secure ## Known Security Considerations ### Current Architecture - **CLI Dependency**: Security depends on Codex CLI installation - **File Access**: MCP tools can access files in specified directories - **Subprocess Calls**: Uses subprocess to call Codex CLI - **Network Requests**: Codex CLI makes network requests to OpenAI ### Mitigation Strategies - **Timeout Protection**: 60-second timeout prevents long-running attacks - **Error Handling**: Graceful error handling without information leakage - **No Persistent State**: Stateless operation reduces attack surface - **Simple Architecture**: Minimal code reduces potential vulnerabilities ## Security Updates ### How We Handle Security Issues 1. **Assessment**: Evaluate the severity and impact 2. **Fix Development**: Develop and test a security fix 3. **Coordinated Disclosure**: Work with reporter on disclosure timeline 4. **Release**: Deploy security update as patch release 5. **Notification**: Notify users through appropriate channels ### Update Notifications Security updates are announced through: - **GitHub Releases**: All releases include security notes - **GitHub Security Advisories**: For significant vulnerabilities - **README Updates**: Security-related changes noted - **CHANGELOG**: Detailed security fix information ## Disclosure Policy ### Responsible Disclosure We follow responsible disclosure practices: - **Private Reporting**: Initial reports should be private - **Coordinated Timeline**: Work together on disclosure timing - **Credit**: Security researchers receive appropriate credit - **Public Disclosure**: After fix is available and deployed ### Timeline Example 1. **Day 0**: Vulnerability reported privately 2. **Day 1-2**: Acknowledgment and initial assessment 3. **Day 3-14**: Fix development and testing 4. **Day 14-21**: Security update release 5. **Day 21+**: Public disclosure (if appropriate) ## Security-Related Dependencies ### Direct Dependencies - **mcp**: Model Context Protocol library - Keep updated to latest stable version - Monitor for security advisories ### External Dependencies - **Codex CLI**: OpenAI's official CLI tool - Security managed by Google - Users should keep updated - Authentication handled by Google ### System Dependencies - **Python**: Use supported Python versions (3.9+) - **Operating System**: Keep OS updated for subprocess security - **Network**: Secure network configuration recommended ## Security Questions For general security questions (non-vulnerabilities): - Check existing documentation first - Use GitHub Discussions for community input - Create GitHub issues for documentation improvements - Email maintainers for sensitive questions ## Acknowledgments We thank the security research community for helping keep Codex Bridge secure: - [Future security researchers will be listed here] ## Resources ### Security Tools and Resources - [OWASP Top 10](https://owasp.org/www-project-top-ten/) - [Python Security Guidelines](https://python.org/dev/security/) - [GitHub Security Features](https://docs.github.com/en/code-security) - [MCP Security Considerations](https://modelcontextprotocol.io/) --- **Remember**: When in doubt about security, it's better to report a false positive than to ignore a potential vulnerability.
