KubePi is a Kubernetes multi-cluster management panel. In versions up to and including 2.0.0, cluster-scoped APIs do not consistently validate per-cluster access, allowing an authenticated user with cluster management permissions to operate on clusters outside the scope they were granted. Because the affected endpoints act on cluster-specific data without confirming that the requesting user is authorized for that particular cluster, a user assigned management rights over one cluster can, under certain role and cluster configurations, read or modify data in clusters they should not manage. This issue is fixed in version 2.0.1.
