## Affected components
- Packagist phpmyfaq/phpmyfaq: affected <= 3.1.12
- Packagist thorsten/phpmyfaq: affected <= 3.1.12

## Suggested inspection (read-only)
- Packagist phpmyfaq/phpmyfaq: check the installed version with your package manager.
- Packagist thorsten/phpmyfaq: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on phpmyfaq/phpmyfaq, thorsten/phpmyfaq.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
