CVE-2026-126730: Drupal Authenticator Login Plus authentication bypass in 2FA

CVE-2026-126730 · Severity: info · Published 2026-11-11

Authenticator Login Plus is a Drupal module that enforces two-factor authentication using time-based one-time passwords from authenticator apps. The module fails to properly verify the second factor, allowing attackers who obtain a first-factor credential (such as a valid one-time login link) to bypass the 2FA requirement and perform privileged actions like updating account details and triggering other modules' login hooks.

Technical details

The vulnerability is an authentication bypass in the 2FA enforcement logic. An attacker with only the first authentication factor (a valid one-time login link or valid first-factor authentication through another module) can trigger actions that require full authentication, including updating the account's last login time and executing other modules' login hooks. The attack requires prior compromise of the first factor and the impact is amplified by reactions from other installed modules.
