CVE-2025-13539Network attack vector

Administrator impersonation via misbound social login

Published Nov 27, 2025 · Updated Nov 27, 2025

Authentication bypass in Elated Themes FindAll Membership 1.0.4 and earlier allows remote attackers to obtain administrator sessions. The findall_membership_check_facebook_user and findall_membership_check_google_user functions establish a session without properly binding the logged-in user to the previously verified identity data. Exploitation requires an existing site account and an administrator's email address; the default temporary-user flow permits account creation.
