Technical details
This authentication bypass vulnerability in the Authenticator Login Plus module (drupal/auth_login_plus) allows an attacker to make the module treat a login as having passed password verification when it did not, or to access the 2FA setup page of another account. The vulnerability is exploitable via a timing-dependent race condition and requires the attacker to have an existing account on the site and either control the victim's email address or know their password. Exploitation could result in account takeover of accounts with 2FA enabled.
