Mitigation direction
- Identify all Crafter CMS 3.1 deployments and associated crafter-search services.
- Restrict crafter-search access to authenticated, trusted administrative paths only.
- Remove public or broad internal network exposure for crafter-search.
- Review the Crafter advisory for version-specific upgrade or configuration guidance.
