GHSA-phhq-63jg-fp7r: Contrast vulnerability allows arbitrary host data Injection into container VOLUME mount points

July 9, 2025

All of the following need to be true to be affected by this vulnerability:

  1. A bare metal Contrast deployment (AKS is not affected).
  2. An image with at least one VOLUME directive.
  3. No Kubernetes mount at the path of the VOLUME.

If these are all true, the host is able to write arbitrary trees below that mount point.
