Summary

Velero prior to 1.18.1 has a vulnerability that allows an attacker who compromises the backup object-storage backend to 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.

Risk Assessment

An attacker could overwrite critical files in the Velero pod, potentially leading to system integrity compromise or malicious code execution in the Velero context.

Recommendation

Upgrade Velero to version 1.18.1 or later and secure the object storage backend.
