FKIE_CVE-2025-13587

Vulnerability from fkie_nvd - Published: 2026-02-19 07:17 - Updated: 2026-06-17 08:34
Severity
6.5 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N
Summary
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.
