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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **RHSA-2026:53263** · Red Hat · fixed in: Red Hat OpenShift AI 3.3 · released 2026-08-11 · [advisory](https://access.redhat.com/errata/RHSA-2026:53263)\n- **RHSA-2026:60520** · Red Hat · fixed in: Red Hat OpenShift AI 3.4 · released 2026-08-27 · [advisory](https://access.redhat.com/errata/RHSA-2026:60520)\n- **RHSA-2026:53262** · Red Hat · fixed in: Red Hat OpenShift AI 3.4 · released 2026-08-11 · [advisory](https://access.redhat.com/errata/RHSA-2026:53262)\n- **RHSA-2026:60367** · Red Hat · fixed in: Red Hat OpenShift AI 3.5 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60367)","depth":"twilight","depthScore":49,"depthScoreParts":{"impact":48.4,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
