An unauthenticated remote attacker can exploit a misconfiguration in the CatalogdHandler, which lacks proper authentication, and the forwarding of the `openshift-session-token` cookie. This allows the attacker to send requests to the in-cluster catalogd service, leading to the disclosure of the internal operator-catalog index and providing a relay into the openshift-catalogd namespace.","state":0,"publishedAt":"2026-09-23T20:48:13.089+00:00","modifiedAt":"2026-10-01T16:35:24.647+00:00","affected":[{"ecosystem":"https://catalog.redhat.com/software/containers/","name":"openshift4/ose-console-rhel9","ranges":[],"versions":[],"rawVersionEvidence":"{\n
