The JS Help Desk – The Ultimate Help Desk & Support Plugin plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.8.8 via the 'exportusereraserequest' due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Subscriber-level permissions and above, to export ticket data for any user.
The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
