What is CVE-2026-18951?
CVE-2026-18951 is a high-severity missing authorization vulnerability in Red Hat OpenShift AI 3.3, published on 10 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
A flaw was found in the Red Hat OpenShift AI (RHOAI) overlay for the training operator. The RHOAI overlay incorrectly aggregates `trainjobs` management permissions into the native Kubernetes `edit ClusterRole`. This allows any user with `edit ClusterRole` permissions in a namespace to create, modify, and delete `TrainJobs`. When combined with a separate vulnerability (TRN-01) that permits arbitrary pod configurations, a remote attacker with namespace editor privileges could exploit this to escalate privileges, potentially leading to arbitrary code execution.
