Kubevirt/virt-cdi-importer, versions 1.4.0 to 1.5.3 inclusive, were reported to disable TLS certificate validation when importing data into PVCs from container registries. This could enable man-in-the-middle attacks between a container registry and the virt-cdi-component, leading to possible undetected tampering of trusted container image content.

A flaw was found in the containerized-data-importer in virt-cdi-cloner, version 1.4, 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.
