CVE-2026-0740
Full vulnerability record from the local CVENow database.
Description
The Ninja Forms - File Uploads plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'NF_FU_AJAX_Controllers_Uploads::handle_upload' function in all versions up to, and including, 3.3.26. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible. Note: The vulnerability was partially patched in version 3.3.25 and fully patched in version 3.3.27.

"value": "El plugin Ninja Forms - File Uploads para WordPress es vulnerable a la carga arbitraria de archivos debido a la falta de validación del tipo de archivo en la función ’NF_FU_AJAX_Controllers_Uploads::handle_upload’ en todas las versiones hasta la 3.3.26, inclusive. Esto permite a atacantes no autenticados cargar archivos arbitrarios en el servidor del sitio afectado, lo que podría posibilitar la ejecución remota de código.
