## Description

The BuddyDrive plugin for WordPress is vulnerable to unauthorized modification of data in all versions up to, and including, 2.1.4 due to a missing authorization check on the destination folder when files and folders are uploaded or edited. This makes it possible for authenticated attackers, with subscriber-level access and above, to place files and folders into folders owned by other users or shared with groups they do not belong to.
