## Description

The MxChat plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.2.25. This is due to missing nonce validation in the transcript message translation AJAX action. This makes it possible for unauthenticated attackers to make a site administrator trigger translations of chat transcripts, which spend the site's AI API credits and store the results. The attacker must trick the administrator into performing an action such as clicking a link.
