Description
A flaw was found in oc-mirror. During mirroring operations, the embedded local cache registry binds to all network interfaces without authentication or encryption instead of restricting access to the local system. An unauthenticated attacker on an adjacent network can connect to the exposed service to push tampered container images, delete cached images, or access mirrored content.
