An attacker with namespace editor privileges can bypass security hardening by submitting a malicious Argo Workflow through the V1 API path. This allows the API server to create pods with elevated privileges, acting as a 'confused deputy' on behalf of the attacker. Successful exploitation grants the attacker node-root access, enabling arbitrary code execution and full control over the underlying node.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **RHSA-2026:65126** · Red Hat · fixed in: Red Hat OpenShift AI 2.25 · released 2026-09-08 · [advisory](https://access.redhat.com/errata/RHSA-2026:65126)\n- **RHSA-2026:53261** · Red Hat · fixed in: Red Hat OpenShift AI 2.25 · released 2026-08-11 · [advisory](https://access.redhat.com/errata/RHSA-2026:53261)\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)","depth":"twilight","depthScore":42,"depthScoreParts":{"impact":41.8,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
