CVE-2026-13731

The WPBot – AI ChatBot for Live Support, Lead Generation, AI Services plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'conversation' parameter in all versions up to, and including, 8.4.9 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 AJAX nonce required to authenticate the save request is publicly emitted on every frontend page via wp_localize_script, making it freely obtainable by any anonymous visitor and removing any practical barrier to exploitation.
