View online: https://www.drupal.org/sa-contrib-2026-119 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] Reported By:  * 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] Coordinated By:  * Swan Kalata (akalata) [9] of the Drupal Security Team * Greg Knaddison (greggles) [10] of the Drupal Security Team * Drew Webber (mcdruid) [11] of the Drupal Security Team ------------------------------------------------------------------------------ Contribution record [12] [1] https://www.drupal.org/project/ai [2] https://www.drupal.org/security-team/risk-levels [3] https://www.drupal.org/project/ai/releases/1.4.8 [4] https://www.drupal.org/project/ai/releases/1.3.13 [5] https://www.drupal.org/u/mcdruid [6] https://www.drupal.org/u/admitriiev [7] https://www.drupal.org/u/marcus_johansson [8] https://www.drupal.org/u/valthebald [9] https://www.drupal.org/u/akalata [10] https://www.drupal.org/u/greggles [11] https://www.drupal.org/u/mcdruid [12] https://new.drupal.org/contribution-record?source_link=https%3A//www.drupal....
