CVE-2026-91182
A flaw was found in open-cluster-management. An agent communicating via the gRPC broker can bypass authorization by manipulating the ce-clustername cloud event header attribute, which is used for authorization, independently of the actual event payload. This allows a registered managed cluster to...
CVE-2026-73267
In Red Hat's multicluster engine, the clusterclaims-controller deletes ManagedClusters based solely on clusterclaim.spec.namespace without verifying ownership. Any tenant with standard ClusterClaim permissions can delete any cluster, including the hub's local-cluster, causing a HIGH-severity (7.7...
