CVE-2026-4393Network attack vector

Forced logout via unprotected CSRF route

Published Mar 26, 2026 · Updated Mar 26, 2026

CSRF in Drupal Automated Logout before 1.7.0 and 2.0.0 through 2.0.1 allows remote attackers to force authenticated users to log out. The module's logout route accepts a session-bearing cross-site request without validating a CSRF token, causing the victim's session to terminate. An authenticated Drupal session must load attacker-controlled content, and the consequence is limited to forced session termination without reported data access or modification.
