We provide security updates for the following versions of Type-Sync:

We take the security of Type-Sync seriously. If you discover a security vulnerability, please follow these steps:

Please do not report security vulnerabilities through public GitHub issues, discussions, or pull requests.

Instead, please report security vulnerabilities via email to: security@type-sync.dev (or create a private security advisory on GitHub)

Please provide as much information as possible, including:

• Type of vulnerability (e.g., code injection, path traversal, etc.)
• Location of the vulnerable code (file path, line number if possible)
• Step-by-step instructions to reproduce the issue
• Potential impact of the vulnerability
• Suggested fix (if you have one)

• Acknowledgment: Within 48 hours
• Initial assessment: Within 1 week
• Fix development: Within 2-4 weeks (depending on complexity)
• Public disclosure: After fix is released and users have time to update

1. Keep Type-Sync updated to the latest version
2. Validate input schemas before processing
3. Sanitize generated output if using in web applications
4. Use HTTPS when fetching schemas from URLs
5. Review generated code before committing to version control

1. Validate all inputs from CLI arguments and configuration files
2. Sanitize file paths to prevent directory traversal
3. Escape output to prevent code injection in generated files
4. Use secure defaults in configuration options
5. Review dependencies for known vulnerabilities

• Generated TypeScript code should be safe by default
• No execution of arbitrary code from schemas
• Proper escaping of schema content in generated code

• Validate output paths to prevent writing outside intended directories
• Proper handling of file permissions
• Safe cleanup of temporary files

• HTTPS validation for remote schema fetching
• Timeout handling for network requests
• No execution of downloaded content

• Regular security audits with npm audit
• Minimal dependency footprint
• Automated dependency updates with security checks

• Malicious schemas: Large or deeply nested schemas could cause DoS
• Code injection: Schema content is escaped before code generation
• Path traversal: Output paths are validated and sanitized

• Argument injection: CLI arguments are properly validated
• File permissions: Generated files inherit safe default permissions

When we receive a security vulnerability report:

1. Confirmation: We confirm the vulnerability and assess its impact
2. Fix development: We develop and test a fix
3. Release preparation: We prepare a security release
4. Coordinated disclosure: We work with the reporter on disclosure timing
5. Public disclosure: We publish details after users have time to update

We currently do not offer a formal bug bounty program, but we greatly appreciate security researchers who responsibly disclose vulnerabilities. We will:

• Acknowledge your contribution in release notes (if desired)
• Provide public credit for the discovery
• Consider featuring your contribution in our security hall of fame
