## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on magick.net-q8-arm64, magick.net-q8-x86, magick.net-q16-hdri-anycpu, magick.net-q16-openmp-x64, magick.net-q16-anycpu, magick.net-q16-hdri-x86, magick.net-q16-hdri-openmp-arm64, magick.net-q16-hdri-arm64, magick.net-q16-x86, magick.net-q8-openmp-x64, magick.net-q16-hdri-openmp-x64, magick.net-q16-openmp-arm64, magick.net-q16-x64, magick.net-q8-x64, magick.net-q8-openmp-arm64, magick.net-q8-anycpu, magick.net-q16-openmp-x86, magick.net-q16-arm64, magick.net-q16-hdri-x64.
- 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.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
