| Doc Text: |
A flaw was found in the Amazon EFS Container Storage Interface (CSI) Driver. When the controller is configured
with the non-default --delete-access-point-root-dir=true option, it does not verify that the EFS access point referenced by a PersistentVolume's volumeHandle belongs to the file system referenced by that same volumeHandle. An authenticated Kubernetes user with PersistentVolume creation privileges could exploit this vulnerability. By crafting a PersistentVolume volumeHandle that pairs an access point from one filesystem with a different target filesystem, an attacker could cause recursive deletion of directories on an Amazon Elastic File System (EFS) filesystem they are not authorized to access. This could lead to a denial of service or data loss.
