CVE-2025-7393Network attack vector

Account access via brute-force protection bypass

Published Jul 21, 2025 · Updated Jul 22, 2025

Improper brute-force protection in Drupal Mail Login 3.0.0 through 3.1.x and 4.0.0 through 4.1.x allows remote attackers to access accounts. The module's login-form rate limiting can be bypassed, but Drupal has not disclosed the specific check or state transition that fails. No authentication is required; repeated password guesses can lead to account access, while the vendor reports no availability impact.
