Affected: Red Hat multicluster engine for Kubernetes 2.10, Red Hat multicluster engine for Kubernetes 2.11, Red Hat multicluster engine for Kubernetes 2.17, Red Hat multicluster engine for Kubernetes 2.6, Red Hat multicluster engine for Kubernetes 2.8, Red Hat multicluster engine for Kubernetes 2.9

A flaw was found in the clusterclaims-controller component of multicluster engine (MCE). A tenant with standard permissions to create and delete ClusterClaim resources can exploit this by manipulating the `spec.namespace` field. This allows the tenant to specify and delete any ManagedCluster, including the hub's local-cluster or other tenants' clusters, due to a missing ownership check. This vulnerability can lead to a denial of service by enabling unauthorized deletion of ManagedClusters.
