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.
