CVE-2026-66793

A flaw was found in the governance-policy-addon-controller component of Red Hat Advanced Cluster Management for Kubernetes.

Impact

A flaw was found in the governance-policy-addon-controller component of Red Hat Advanced Cluster Management for Kubernetes. A user with permissions to annotate the namespaced ManagedClusterAddOn resource can override the governance-policy container image. This allows an attacker to run a controlled image with cluster-admin privileges on the managed cluster, leading to arbitrary code execution and privilege escalation.
