Stored XSS in WPBot AI ChatBot for WordPress Plugin

Publication date: 2026-07-01

Last updated on: 2026-07-01

Assigner: Wordfence

Description
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.

The vulnerability exists in the WPBot – AI ChatBot for Live Support, Lead Generation, AI Services plugin for WordPress, affecting all versions up to and including 8.4.9.

It is a Stored Cross-Site Scripting (XSS) vulnerability caused by insufficient input sanitization and output escaping of the 'conversation' parameter.

Impact Analysis

This vulnerability can allow attackers to execute malicious scripts in the context of the affected website without authentication.

Such script execution can lead to theft of user data, session hijacking, defacement of the website, or redirection to malicious sites.

Because the AJAX nonce is publicly accessible, attackers can exploit this vulnerability easily, increasing the risk and potential impact.
