CVE-2026-73267: Client-Side Enforcement of Server-Side Security in Red Hat Multicluster Engine for KubernetesCVE-2026-73267
0

CVE-2026-73267 is a high-severity vulnerability in the clusterclaims-controller component of Red Hat Multicluster Engine for Kubernetes. It allows a tenant with standard permissions on ClusterClaim resources to manipulate the spec.namespace field to delete any ManagedCluster, including critical clusters such as the hub's local-cluster or other tenants' clusters. This occurs due to a missing ownership check, leading to potential denial of service by unauthorized deletion of ManagedClusters. Currently, no effective mitigation or official fix meeting Red Hat's criteria is available.
