The Download Manager plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the makeMediaPublic() and makeMediaPrivate() functions in all versions up to, and including, 3.3.51. This is due to the functions only checking for edit posts capability without verifying post ownership via current user can('edit post', $id), and the destructive operations executing before the admin-level check in mediaAccessControl(). This makes it possible for authenticated attackers, with Contributor-level access and above, to strip all protection metadata (password, access restrictions, private flag) from any media file they do not own, making admin-protected files publicly accessible via their direct URL.
