CVE-2026-65049
Ninja Forms Cross-Site Network-Wide Data Deletion on WordPress Multisite via nf_delete_all_data AJAX Action
Description
Ninja Forms plugin version 3.14.8 and prior for WordPress Multisite contains an incorrect authorization vulnerability that allows a subsite Administrator to trigger network-wide deletion of all Ninja Forms data by exploiting a site-scoped capability check combined with unsafe multisite migration defaults. Attackers can send a crafted POST request to the admin-ajax.php endpoint with the nf_delete_all_data action and a per-site nonce to invoke migration routines that unconditionally iterate all blogs via switch_to_blog(), dropping all nf3_* tables and clearing options and transients across every subsite in the network without requiring super-admin or network-admin privileges.

Action Type Old Value New Value Added Translation Title: Ninja Forms de Saturday Drive, Description: El plugin Ninja Forms versión 3.14.8 y anteriores para WordPress Multisite contiene una vulnerabilidad de autorización incorrecta que permite a un Administrador de subsitio activar la eliminación de datos a nivel de red de todos los datos de Ninja Forms explotando una comprobación de capacidad con alcance de sitio combinada con valores predeterminados de migración multisitio inseguros. Los atacantes pueden enviar una solicitud POST manipulada al endpoint admin-ajax.php con la acción nf_delete_all_data y un nonce por sitio para invocar rutinas de migración que iteran incondicionalmente todos los blogs a través de switch_to_blog(), eliminando todas las tablas nf3_* y borrando opciones y transitorios en cada subsitio de la red sin requerir privilegios de superadministrador o administrador de red. -
