EPSS Percentile
0th
Unverified ownership of a storage access point in the volume deletion component of the Amazon EFS CSI Driver before v3.4.1 might allow an authenticated Kubernetes user with PersistentVolume creation privileges to cause recursive deletion of directories on an EFS filesystem they are not authorized to access, via a crafted PersistentVolume volumeHandle that pairs an access point from one filesystem with a different target filesystem. To remediate this issue, users should upgrade to version v3.4.1.
