Summary

A flaw was found in the RHOAI training-operator. This vulnerability allows a user with standard edit or admin roles in any Kubernetes namespace to escalate their privileges.

Through the creation of training jobs, an attacker can impersonate service accounts, access the host filesystem, and potentially execute arbitrary code remotely. This issue arises from the aggregation of training job permissions onto native Kubernetes edit and admin ClusterRoles, coupled with unrestricted PodTemplateSpec passthrough.

This is a Critical vulnerability. This allows any namespace editor to escalate privileges by creating training jobs that can impersonate ServiceAccounts, mount hostPath volumes, set privileged security contexts, and achieve remote code execution, expanding the attack surface beyond users explicitly granted training workload access.

Red Hat severity: Critical — CVSS 8.8 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-250.

Affected Red Hat products: Red Hat OpenShift AI 2.25; Red Hat OpenShift AI 3.3; Red Hat OpenShift AI 3.4; Red Hat OpenShift AI 3.5. Red Hat fixing advisory: RHSA-2026:53261, RHSA-2026:53263, RHSA-2026:53262, RHSA-2026:60520, RHSA-2026:60367.
