CVE, Research URL: CVE-2025-13587
Home page URL: Security reports for Two Factor (2FA) Authentication via Email
Application: Two Factor (2FA) Authentication via Email
Date: Feb 19, 2026
Research Description: The Two Factor (2FA) Authentication via Email plugin for WordPress is vulnerable to Two-Factor Authentication Bypass in versions up to, and including, 1.9.8. This is because the SS88_2FAVE::wp_login() method only enforces the 2FA requirement if the 'token' HTTP GET parameter is undefined, which makes it possible to bypass two-factor authentication by supplying any value in the 'token' parameter during login, including an empty one.
Affected versions: max 1.9.9.
Status: vulnerable
