CVE-2026-10059 is an incorrect privilege-assignment flaw in the Multicluster Engine for Kubernetes ClusterCurator controller. A tenant administrator with namespace-scoped privileges can create a namespaced ClusterCurator resource that causes the controller to create cluster-scoped RBAC permissions for a ServiceAccount in the tenant-controlled namespace. The tenant can then mint a token for that ServiceAccount, obtaining cluster-wide administrative authority and bypassing Kubernetes namespace-isolation boundaries.
