CVE-2025-13986Network attack vectorHinoki check available

Authenticated login bypass via unguarded REST routes

Published Jan 28, 2026 · Updated Jan 28, 2026

Authentication bypass in Drupal Disable Login Page before 1.1.3 allows remote authenticated users to log in through REST/HTTP routes. The module protects the HTML /user/login form but omits its access requirement from /user/login?_format=json and other programmatic authentication routes. Valid account credentials are required; successful requests bypass the configured secret-key gate but do not create new privileges.
