Doc Text:
A flaw was found in the containerized-data-importer where the host-assisted cloning feature does not determine whether the requesting user has permission to access the Persistent Volume Claim (PVC) in the source namespace. This could allow users to clone any PVC in the cluster into their own namespace, effectively allowing access to other user's data.

Description Pedro Sampaio 2019-06-17 18:32:01 UTC
A flaw was found in the containerized-data-importer. The host-assisted cloning feature don't limit which namespaces can be involved in a clone
operation, permitting users to clone any PVC in the cluster into their own namespace. This effectively allows user read access to all storage currently allocated to PVCs regardless of namespace.
