CVE-2022-3248Network attack vector

Unauthorized ingress hostnames via admission-check bypass

Published Oct 5, 2023 · Updated Aug 29, 2024

Incorrect authorization in affected Red Hat OpenShift products allows remote authenticated users to set unauthorized ingress hostnames. After custom-host permission is revoked, OpenShift API admission checks fail to reject certain ingress objects whose requested hostnames cross that policy boundary. Exploitation requires project-administrator access; the reported consequence is an unauthorized routing configuration, with no reported disclosure or service interruption.
