CVE-2025-64433Public exploitNetwork attack vector

Container file disclosure via PVC symlink following

Published Nov 7, 2025 · Updated Nov 7, 2025

Path traversal in KubeVirt before 1.5.3 and KubeVirt 1.6.0 allows remote authenticated users to read virt-launcher pod files. The host-disk PVC mount code follows attacker-created symlinks outside the volume, changes the target file to UID 107, and exposes it as a libvirt block device. Exploitation requires control over PVC contents and the ability to attach that PVC to a VM; the result is confidentiality loss only.
