  "title": "Authorization bypass in Quay registry key rotation",
  "summary": "Red Hat Quay 3 has an authorization flaw in its registry signing-key rotation handling. A remote unauthenticated attacker able to reach an affected service and obtain an anonymous registry token may cause the registry to trust an attacker-controlled signing key, enabling access to private images and modification of repository tags.",
  "mitigation": "Immediately restrict unauthenticated network access to affected Quay instances, especially the key-rotation service endpoint, using network controls. Audit for unauthorized signing keys and repository tag changes, rotate affected signing keys, and apply vendor remediation when it becomes available.",
