CVE-2026-14291Public exploitNetwork attack vector

Password-only account takeover via unchecked 2FA skip

Published Jul 23, 2026 · Updated Jul 23, 2026

Authentication bypass in WP Security Ninja Premium before 5.290 allows remote attackers with a user's password to skip enforced 2FA. The secnin_skip_2fa AJAX action accepts the challenge's temp_token and issues a logged-in session cookie without validating an OTP. The premium 2FA module must be enabled, and knowledge of any target account's password grants access as that account, including as an administrator.
