Affected versions of this package are vulnerable to Access Control Bypass. Project members have continued access to create, update, read, and delete namespaces in a project after they have been removed from it. Furthermore, any project member with access to the default namespace can mount the netes-default service account in a pod, and then use that pod to execute administrative privileged commands against the k8s cluster.
