Why this deserves its current priority

CVSS is 9.8. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Red Hat/quay/quay-rhel8, Red Hat/quay/quay-rhel9.
  2. 2Review the reported fix. Source-reported workaround: Restrict access to the /keys endpoint at the proxy or load balancer so only trusted internal components can reach it. Review audit logs for service_key_rotate and service_key_delete events with a null expiration_date, and remove any unrecognised approved service keys. Deleting a rogue key is not durable until a fixed build is deployed, because the anonymous request can install a new key.

Upstream source description

A flaw was found in Red Hat Quay. An unauthenticated client can obtain an anonymous registry token with an audience it controls, present that token to the service key rotation endpoint, and install its own approved signing key with no expiry. Registry tokens signed with that key are accepted for any repository, allowing read and write access to private images and replacement of repository tags.
