Technical details
The Drupal AI module and several submodules (including AI Automators, AI Translate, AI API Explorer, and AI Content Suggestions) fail to properly neutralize input when rendering HTML or Markdown generated by Large Language Models (LLMs). An attacker can exploit this by injecting malicious payloads into prompts that, when processed by the LLM and previewed in a browser, result in Cross-Site Scripting (XSS) or the disclosure of secret communications within the LLM request context. The attack requires the ability to influence the text sent to the LLM. The issue is resolved in versions 1.2.17, 1.3.8, and 1.4.3.
Affected products
- Drupal AI (Artificial Intelligence) 0.0.0 to 1.2.16, 1.3.0 to 1.3.7, 1.4.0 to 1.4.2
