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.","severity":{"version":"3.1","score":8.8,"vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","level":"high","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-09","score":0.00915,"percentile":0.6039,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-267","CWE-284"],"published":"2026-08-10T20:45:10Z","modified":"2026-09-30T18:33:41Z","products":[{"vendor":"red hat","product":"red hat openshift ai 3.3"},{"vendor":"red hat","product":"red hat openshift ai 3.4"},{"vendor":"red hat","product":"red hat openshift ai 3.5"}],"references":[{"url":"https://access.redhat.com/errata/RHSA-2026:53262","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2026:53263","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2026:60367","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2026:60520","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2026:73987","tags":["vendor-advisory","x_refsource_REDHAT"]},{"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","tags":["issue-tracking","x_refsource_REDHAT"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-18951"},{"url":"https://github.com/advisories/GHSA-h7xh-qc2m-rc58"}],"sources":{"cve":[{"id":"CVE-2026-18951","title":"Odh-training-operator-rhel9: [trainer v2 security] trn-02: rhoai overlay aggregates trainjobs crud into standard edit clusterrole","description":"A flaw was found in the Red Hat OpenShift AI (RHOAI) overlay for the training operator.
