CVE-2026-18260Network attack vector

Login-form access via unrestricted secret-key guessing

Published Aug 25, 2026 · Updated Aug 25, 2026

Access bypass in Drupal Disable Login Page before 1.1.4 allows remote attackers to expose the login form by guessing its secret key. The access check accepts the administrator-configured query parameter without imposing a retry limit, so an arbitrary-length sequence of key guesses reaches the same login route. The restriction must be enabled, and a successful guess reveals only the login form; valid account credentials are still required to authenticate.
