MFA bypass via unprotected login routes
Published May 14, 2025 · Updated May 19, 2025
Authentication bypass in Drupal Enterprise MFA - TFA before 4.7.0 and from 5.0.0 before 5.2.0 allows remote attackers to skip MFA. The module fails to ensure that known Drupal login routes invoke its second-factor checks after password authentication. An attacker must possess a valid username and password; successful exploitation grants the account's Drupal access without completing the configured second factor.
