Project: AI (Artificial Intelligence) [1]
Date: 2026-September-02
Security risk: *Moderately critical* 10 ∕ 25
AC:Complex/A:Admin/CI:Some/II:Some/E:Theoretical/TD:Uncommon [2]
Vulnerability: Cross site scripting

Affected versions: <1.3.13 || >=1.4.0 <1.4.8
CVE IDs: CVE-2026-84911
Description: 
This AI Chatbot module enables you to have a Chatbot using assistants to help
you with your Drupal website.

The module doesn't sufficiently sanitize for cross site scripting (XSS) when
using the structured results using legacy agent setups.

This vulnerability is mitigated by the fact that an attacker must be able to
invoke a prompt injection set via editorial content and the site must have
been setup using AI 1.0.x and AI Agents 1.0.x branch using a uncommon
configuration. Any configuration setup or updated after these minor versions
are not affected.

Solution: 
Install the latest version:

 * If you use the AI module 1.4.7 or below upgrade to AI module 1.4.8 [3]
 * If you use the AI module 1.3.12 or below upgrade to AI module 1.3.13 [4]

 * Drew Webber (mcdruid) [5] of the Drupal Security Team

Fixed By: 
 * Artem Dmitriiev (a.dmitriiev) [6]
 * Marcus Johansson (marcus_johansson) [7]
 * Valery Lourie (valthebald) [8]

 * Swan Kalata (akalata) [9] of the Drupal Security Team
