Description
Improper neutralization of argument delimiters in the volume handling component in AWS EFS CSI Driver (aws-efs-csi-driver) v3.1.0 through v3.4.2 might allow remote authenticated users with PersistentVolume creation permissions to inject arbitrary mount options via comma-separated values in the mounttargetipmap volumeAttribute.
