Summary
AWS EFS CSI Driver Mount Option Injection
Details

Improper neutralization of argument delimiters in the volume handling component in AWS EFS CSI Driver (aws-efs-csi-driver) before v3.0.1 allows remote authenticated users with PersistentVolume creation permissions to inject arbitrary mount options via comma injection.

To remediate this issue, users should upgrade to version v3.0.1
