CVE-2026-66793: Improper Input Validation in Red Hat Red Hat Advanced Cluster Management for Kubernetes 2CVE-2026-66793 0 CVE-2026-66793 is a high-severity vulnerability in the governance-policy-addon-controller component of Red Hat Advanced Cluster Management for Kubernetes 2. It allows a user with namespace-level annotate permissions on the ManagedClusterAddOn resource to override the governance-policy container image. This enables execution of arbitrary code with cluster-admin privileges on the managed cluster, resulting in privilege escalation and potential full cluster compromise. The vulnerability does not require user interaction and has a low attack complexity. Mitigation involves restricting annotate permissions on ManagedClusterAddOn resources to trusted administrators only.
