CVE-2022-3477Known exploitationPublic exploitNetwork attack vector

Account takeover via email-only Facebook login

Published Nov 14, 2022 · Updated Apr 30, 2025

Improper authentication in tagDiv Composer before 3.5 allows remote attackers to take over any WordPress account via its email address. The td_ajax_fb_login_user AJAX action accepts user[email] and establishes that user's authenticated session without validating Facebook identity. No authentication or user interaction is required, but the target account's email address must be known; access receives that account's permissions.
