CVE-2026-101295

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.

In openshift/oc-mirror, the tool incorrectly verifies PGP release image signatures by checking for signature errors before the entire signed body is processed, leading to a bypass of signature verification. A remote attacker, by intercepting or manipulating network traffic to the signature endpoint, could craft a PGP message with a valid Red Hat release key ID but a forged signature, enabling the oc-mirror tool to accept and mirror a malicious release payload into a disconnected registry.
