Descriptions

The Forminator plugin for WordPress is vulnerable to arbitrary file uploads due to insufficient blacklisting on the 'forminator_allowed_mime_types' function in versions up to, and including, 1.27.0. This makes it possible for authenticated attackers with administrator-level capabilities or above to upload arbitrary files on the affected site's server, but due to the htaccess configuration, remote code cannot be executed.

El complemento Forminator para WordPress es vulnerable a la carga de archivos arbitrarios debido a una lista negra insuficiente en la función 'forminator_allowed_mime_types' en versiones hasta la 1.27.0 incluida. Esto hace posible que atacantes autenticados con capacidades de nivel de administrador o superiores carguen archivos arbitrarios en el servidor del sitio afectado, pero debido a la configuración de htaccess, el código remoto no se puede ejecutar.
