## Description

The BuddyDrive plugin for WordPress is vulnerable to Sensitive Information Exposure via the buddydrive_get_bpobjects AJAX action in all versions up to, and including, 2.1.4, due to the user-supplied user_id parameter being used without an authorization check when groups are looked up. This makes it possible for authenticated attackers, with subscriber-level access and above, to list the BuddyDrive-enabled groups, including hidden groups, that any other user belongs to.
