This is due to a missing capability check on the 'updateUser' branch of the package_app_action AJAX endpoint, where the handler only validates a nonce and the dispatcher invokes Schedule::updateUser() with the $administrator argument hard-coded to 1, bypassing the only owner-restriction check inside that function and allowing the target user to be determined solely by attacker-supplied input passed directly to wp_update_user(). This makes it possible for authenticated attackers, with Editor-level access and above, to change the email address and password of any account, including Administrator accounts, resulting in a full site takeover."}, {"lang": "es", "value": "El plugin Booking Package para WordPress es vulnerable a escalada de privilegios a trav\u00e9s de toma de control de cuenta en versiones hasta la 1.7.16, inclusive.
