We take security vulnerabilities seriously and appreciate responsible disclosure from security researchers and users. If you discover a security vulnerability in this project, please follow these guidelines:

• Private Reporting: Contact the maintainers directly at [email protected] with detailed information about the vulnerability
• Avoid Public Disclosure: Do not create public GitHub issues for security vulnerabilities until a fix has been developed and deployed
• Complete Information: Include reproduction steps, proof-of-concept code, screenshots, and any other relevant technical details

• Initial Response: We will acknowledge receipt of your report within three business days
• Investigation: A thorough investigation and response plan will be provided within 10 business days
• Critical Issues: Severe vulnerabilities may require expedited handling and will be prioritized accordingly

• Main Branch: The main branch receives all security updates and patches as they become available
• Recent Releases: Tagged releases from the last six months continue to receive security patches for critical vulnerabilities
• Legacy Versions: Older versions are not actively supported and users should upgrade to receive security fixes

This project follows established security frameworks and best practices:

• OWASP Guidelines: Adherence to the OWASP Top Ten vulnerability categories and the OWASP Application Security Verification Standard (ASVS)
• Secure Development Lifecycle: Integration of security considerations throughout the development process

• External Data Sources: All external data, including RSS feeds, URL parameters, and environment variables, must be validated and sanitized before processing
• Type Safety: Utilize TypeScript's type system effectively by starting with unknown types and narrowing them through proper validation
• Content Sanitization: Any dynamic HTML content must be properly sanitized using OWASP-approved sanitization libraries before rendering

• Dependency Management: Maintain current dependencies and regularly audit for known vulnerabilities using npm audit
• Package Vetting: Evaluate third-party packages for security track record, maintenance status, and community reputation before integration
• Transport Security: Enforce HTTPS for all external communications and verify SSL/TLS certificates when making outbound requests
• Secret Management: Store sensitive configuration data outside the repository and implement proper secret rotation procedures

Execute the following security checks before deploying any changes to production:

• Code Quality: Run npm run lint, npm run build, and npm audit to ensure code quality and identify security vulnerabilities
• Content Inspection: Review the generated public/feeds.json file for potentially malicious URLs or content injection attempts
• Dependency Integrity: Maintain the integrity of package-lock.json to prevent dependency tampering and ensure reproducible builds
• Branch Protection: Implement branch protection rules requiring status checks and preventing direct commits to main branches

In the event of a security compromise:

1. Immediate Response: Take the affected system offline and implement emergency patches as quickly as possible
2. Communication: Notify relevant stakeholders about the incident, including the scope of impact and remediation timeline
3. Documentation: Create a detailed incident postmortem documenting the root cause, impact assessment, and steps taken to resolve the issue
4. Process Improvement: Update security procedures and controls based on lessons learned to prevent similar incidents

Maintain security vigilance through continuous monitoring, regular security assessments, and adherence to established security protocols. Remember that security is an ongoing process rather than a one-time implementation.
