CVE-2026-3477
PZ Frontend Manager <= 1.0.6 - Missing Authorization to Arbitrary User Deletion via 'dataType' Parameter
Description
The PZ Frontend Manager plugin for WordPress is vulnerable to Missing Authorization in all versions up to and including 1.0.6. The pzfm_user_request_action_callback() function, registered via the wp_ajax_pzfm_user_request_action action hook, lacks both capability checks and nonce verification. This function handles user activation, deactivation, and deletion operations. When the 'dataType' parameter is set to 'delete', the function calls wp_delete_user() on all provided user IDs without verifying that the current user has the appropriate permissions. Notably, the similar pzfm_remove_item_callback() function does check pzfm_can_delete_user() before performing deletions, indicating this was an oversight. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary WordPress users (including administrators) by sending a crafted request to the AJAX endpoint.

Action Type Old Value New Value Added Translation Title: plugin para WordPress PZ Frontend Manager, Description: El plugin PZ Frontend Manager para WordPress es vulnerable a la falta de autorización en todas las versiones hasta la 1.0.6 inclusive. La función pzfm_user_request_action_callback(), registrada a través del hook de acción wp_ajax_pzfm_user_request_action, carece tanto de comprobaciones de capacidad como de verificación de nonce. Esta función gestiona las operaciones de activación, desactivación y eliminación de usuarios. Cuando el parámetro 'dataType' se establece en 'delete', la función llama a wp_delete_user() en todos los ID de usuario proporcionados sin verificar que el usuario actual tenga los permisos adecuados. Cabe destacar que la función similar pzfm_remove_item_callback() sí comprueba pzfm_can_delete_user() antes de realizar eliminaciones, lo que indica que fue un descuido. Esto hace posible que atacantes autenticados, con acceso de nivel Suscriptor y superior, eliminen usuarios arbitrarios de WordPress (incluidos los administradores) enviando una solicitud manipulada al endpoint AJAX. -
