Description
Velero is an open source tool for backing up, restoring, and migrating Kubernetes cluster resources and persistent volumes. Prior to 1.18.1, an attacker who compromises the backup object-storage backend can upload a malicious backup tarball containing parent-directory paths that escape the extraction directory during restore and overwrite sensitive files in the Velero pod filesystem. This issue is fixed in version 1.18.1.
