A flaw was found in Kubernetes kube-controller-manager. The StatefulSet controller restores ControllerRevision data onto the whole StatefulSet object, including metadata. A user with namespace-scoped write access to StatefulSet and ControllerRevision can cause the controller to create a pod in another namespace. That pod is deleted by garbage collection unless the attacker can name the UID of a StatefulSet in the target namespace.
