CVE-2024-56000Network attack vector

Unauthenticated account takeover via unverified Facebook login data

Published Feb 18, 2025 · Updated Apr 29, 2026

Authentication bypass in SeventhQueen K Elements before 5.4.0 allows remote attackers to take over any WordPress account via its email address. The kleo_fb_intialize function trusts attacker-controlled FB_userdata fields, looks up the supplied email, and passes the resulting user ID to wp_set_auth_cookie without verifying a Facebook access token. No authentication or user interaction is required, but the target account's email address must be known; successful exploitation grants that account's WordPress privileges.
