      <title>CVE-2026-66793 — Governance-policy-addon-controller: governance-policy-addon-controller: arbitrary container image override via managedc…</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-66793</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Red Hat Advanced Cluster Management for Kubernetes 2.11, Red Hat Advanced Cluster Management for Kubernetes 2.13, Red Hat Advanced Cluster Management for Kubernetes 2.14, Red Hat Advanced Cluster Management for Kubernetes 2.15, Red Hat Advanced Cluster Management for Kubernetes 2.16, Red Hat Advanced Cluster Management for Kubernetes 2.17&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;</description>
