Project: One Time Password [1] Date: 2025-May-14 Security risk: *Moderately critical* 14 ∕ 25 AC:Complex/A:None/CI:Some/II:Some/E:Theoretical/TD:Default [2] Vulnerability: Access bypass

Affected versions: <1.3.0 CVE IDs: CVE-2025-48011 Description:  This module enables you to allow users to include a second authentication method in addition to password authentication.

The module doesn't sufficiently prevent TFA from being bypassed when using the REST login routes.

A new requirements check has been added to the status report so other authentication providers can be assessed to check if they also allow for this bypass.

This vulnerability is mitigated by the fact that an attacker must obtain a valid username/password.

Solution:  Install the latest version:

* If you use the One Time Password module for Drupal, upgrade to One Time Password 8.x-1.3 [3]
