Official description

The MxChat – AI Chatbot & Content Generation for WordPress plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via the 'feedback' parameter in all versions up to, and including, 3.2.25 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The stored payload is written by any unauthenticated visitor via a single POST to admin-ajax.php and detonates automatically when any administrator next loads the Transcripts page.
