NVD Description

Note: Versions mentioned in the description apply only to the upstream docker-machine-driver-harvester package and not the docker-machine-driver-harvester package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

A flaw was found in KubeVirt's virt-exportserver component. An attacker with specific namespace-level access can exploit a path traversal vulnerability in the VMExport directory endpoint. By placing a symbolic link (symlink) within an exported filesystem Persistent Volume Claim (PVC) that points outside its designated mount root, the attacker can read arbitrary files from the exporter pod's filesystem. This leads to information disclosure, potentially exposing sensitive data.
