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."}], "affected": [{"vendor": "Red Hat", "product": "Red Hat OpenShift AI (RHOAI)", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "rhoai/odh-training-operator-rhel9", "defaultStatus": "affected", "cpes": ["cpe:/a:redhat:openshift_ai"]}], "references": [{"url": "https://access.redhat.com/security/cve/CVE-2026-18951", "tags": ["vdb-entry", "x_refsource_REDHAT"]}, {"url": "https://bugzilla.redhat.com/show_bug.cgi?id=2511187", "name": "RHBZ#2511187", "tags": ["issue-tracking", "x_refsource_REDHAT"]}], "datePublic": "2026-08-10T18:54:28.946Z", "workarounds": [{"lang": "en", "value": "Administrators should review and adjust their Kubernetes RBAC configurations within Red Hat OpenShift AI to ensure that `trainjobs` permissions are explicitly managed.
