Threats Tagged 'cve-2026-73267'

CVE-2026-73267 is a vulnerability in the clusterclaims-controller component of Red Hat multicluster engine for Kubernetes 2.10. It allows a tenant with standard permissions to create and delete ClusterClaim resources to manipulate the spec.namespace field and 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 and can lead to denial of service by unauthorized deletion of ManagedClusters.

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.
