CVE-2026-17107
Red Hat multicluster engine for Kubernetes 2.1, multicluster engine for Kubernetes 2.11.0, multicluster engine for Kubernetes 2.17 취약점
A flaw was found in the cluster-proxy service-proxy component used in Red Hat Advanced Cluster Management for Kubernetes (RHACM) and multicluster-engine (MCE). The service-proxy appends impersonation group headers to proxied requests without first removing caller-supplied values, and the spoke ServiceAccount holds unrestricted impersonation permissions. An authenticated hub principal can inject an Impersonate-Group header to escalate to cluster-admin on every managed cluster.
