View online: https://www.drupal.org/sa-contrib-2023-030 Project: Two-factor Authentication (TFA) [1] Date: 2023-July-12 Security risk: *Critical* 17∕25 AC:Basic/A:None/CI:Some/II:Some/E:Proof/TD:All [2] Vulnerability: Access bypass Affected versions: ^1 <= 1.0.0 Description:  This module enables you to allow and/or require users to use a second authentication method in addition to password authentication. The module doesn't sufficiently ensure all core login routes, including the password reset page, require a second factor credential. This vulnerability is mitigated by the fact that an attacker must obtain a first-factor login credential. Solution:  Install the latest version: * If you use the Two-factor Authentication (TFA) module for Drupal 8/9 please upgrade to TFA 8.x-1.1 [3] Ensure all additional external forms of authentication, such as REST, have been disabled.
