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.
Fix
Nothing published yet: no patch, vendor advisory or mitigation reference on NVD, no vendor advisory in the News for this CVE, not in CISA's KEV, no fixed package version. BaselineWatch does not guess at one.
