CVE-2026-16745Network attack vector

Cluster user impersonation via unvalidated forwarded token

Published Jul 23, 2026 · Updated Jul 23, 2026

Authentication bypass in Red Hat OpenShift AI 2.25, 3.3, and 3.4 allows remote authenticated users to impersonate any user. The odh-dashboard backend binds to 0.0.0.0:8080 and accepts x-forwarded-access-token without validating that kube-rbac-proxy supplied it. An attacker must control a pod in the cluster; successful impersonation grants the selected user's Kubernetes API permissions, including any associated data access or code-execution privileges.
