CVE-2025-31677Network attack vector

Data exposure and modification via unprotected Deepchat requests

Published Mar 31, 2025 · Updated Apr 29, 2025

CSRF in Drupal AI 1.0.0 through 1.0.1 allows remote attackers to send Deepchat requests through a privileged user's browser. The Deepchat endpoint accepts chatbot requests without validating a CSRF token, so a hostile site can reuse the browser's active Drupal session. Exploitation requires user interaction and a session with Deepchat and assistant permissions; permissive CORS enables indexed-data disclosure, while configured agents can expose or modify site configuration.
