• Active: Full security and bug fixes
• Security Only: Security fixes only
• Unsupported: No updates, upgrade required

We follow responsible disclosure practices:

1. Report: Security issues reported privately
2. Acknowledgment: We acknowledge within 24 hours
3. Collaboration: We work with reporters on fixes
4. Credit: Reporters credited in advisories
5. Disclosure: Coordinated public disclosure

For significant vulnerabilities:

1. Request CVE ID from MITRE
2. Develop and test patch
3. Prepare security advisory
4. Coordinate release date
5. Publish CVE details

Security advisories follow this format:

# Security Advisory: [Title]
