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.
