Quay: red hat quay: unauthenticated registry signing-key takeover via service key rotation

No exploitation reported by the sources we read.

  • Published2026-11-11
  • WeaknessCWE-1287

Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

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.
