CVE-2025-13981Network attack vectorHinoki check available

Script execution via unfiltered LLM responses

Published Jan 28, 2026 · Updated Jan 28, 2026

Cross-site scripting in Drupal AI before 1.0.7, 1.1.0 through 1.1.6, and 1.2.0 through 1.2.3 allows attackers to run script. The module passes LLM responses derived from prompt-injected user-generated context to web output without sufficient filtering. Exploitation requires remote authenticated users to influence content used as LLM context and a user to view the resulting response, enabling script execution in that user's browser.
