Description

Description

The ability to enumerate users was possible without relevant permissions due to different exception messages depending on whether the user existed or not.

Resolution

We now ensure that a generic message is returned whether the user exists or not if the password is invalid or if the user does not exist.

The patch for this issue is available here for branch 2.10.x and 2.x.
