Project: Disable Login Page [1]
Date: 2025-December-03
Security risk: *Critical* 15 ∕ 25
AC:Complex/A:None/CI:Some/II:Some/E:Theoretical/TD:All [2]
Vulnerability: Access bypass

Affected versions: <1.1.3
CVE IDs: CVE-2025-13986
Description: 
This module enables you to disable the standard Drupal login form
(/user/login) so site owners can prevent interactive logins via the UI.

The module does not sufficiently block authentication when the REST/HTTP
login route is used. An attacker (or legitimate user) with valid credentials
can authenticate using the REST login endpoint (/user/login?_format=json) or
other HTTP-based authentication routes, effectively bypassing the module’s
protection of the UI login page.

This vulnerability is mitigated by the fact that an attacker must already
possess valid account credentials.

Solution: 
Install the latest version:

  * If you use the Disable Login Page module, upgrade to Disable Login Page
    1.1.3 [3]
