The WPQA Builder Plugin WordPress plugin before 5.2, used as a companion plugin for the Discy and Himer , does not validate that the message_id of the wpqa_message_view ajax action belongs to the requesting user, leading to any user being able to read messages for any other users via a Insecure Direct Object Reference (IDOR) vulnerability.
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.
