DescriptionCVE.org
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, 8.7.3 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 action is gated only by a nonce that is localized into every public-facing page via wp_localize_script, rendering the nonce check ineffective as an access control barrier for unauthenticated users.
