Vulnerabilidad · Publicado 15/08/2026
El plugin Wholesale Market para WordPress (versiones hasta 2.2.2) contiene una vulnerabilidad de escalada de privilegios mediante la acción AJAX ced_wholesale_request_send. El defecto en la validación del nonce y autenticación permite a usuarios autenticados elevar sus permisos sin restricciones. Afecta tiendas de comercio electrónico en LATAM que utilizan este complemento para gestión de ventas mayoristas.
The Wholesale Market plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 2.2.2 via the ced_wholesale_request_send AJAX action. The ced_wholesale_request_send_callback() handler only verifies a nonce (which is exposed to any authenticated user through wp_localize_script on the frontend) and that the caller has a positive user ID, then calls WP_User::add_role() with the client-supplied role_required POST parameter without restricting the value to an allowlist of wholesale roles. This makes it possible for authenticated attackers, with Subscriber-level access and above, to elevate their privileges to Administrator when the site administrator has enabled the 'Assigning requested role directly' option.
