Vulnerabilidad · Publicado 19/09/2026
El plugin Gravity Forms para WordPress es vulnerable a carga arbitraria de archivos en versiones hasta 3.1.0.4. Un defecto en la validación de extensiones permite eludir controles de seguridad en campos ocultos de carga, exponiendo servidores a ejecución de código remoto. Afecta principalmente a empresas, agencias digitales y e-commerce en LATAM que dependen de formularios de contacto y recopilación de datos en WordPress.
The Gravity Forms plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 3.1.0.4 via the upload_file function. This is due to a mismatch between the field validation pipeline and the file persistence pipeline, where hidden file upload fields bypass extension validation and a rejected file's intact upload state is later passed to upload_file() without re-validation. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible. Exploitation requires the targeted form to contain a File Upload field with its Visibility set to 'Hidden'; the vulnerability is reachable by unauthenticated attackers on any publicly accessible form meeting this condition.
