Overview
Affected versions of this package are vulnerable to Missing Authorization via the content-locking process. An attacker can obtain email addresses and identifiers of users who should be inaccessible by sending requests as an authenticated user with restricted users.access or users.list permissions. This is only exploitable if the authenticated user's role is configured to restrict access or listing of other users.
