CVE-2022-4305Public exploitNetwork attack vector

Unauthenticated Administrator access via return AJAX action

Published Jan 23, 2023 · Updated Apr 3, 2025

Privilege escalation in WP-Buy Login as User or Customer before 3.3 allows remote attackers to obtain a valid Administrator session. The loginas_return_admin AJAX action trusts the attacker-supplied loginas_old_user_id cookie and restores that account without verifying authorization. No account is required; setting the cookie to an administrator ID and invoking the action grants control of that WordPress account.
