Vulnerabilidad · Publicado 15/08/2026
El plugin RapiSafe – Secure Multi File Upload for Contact Form 7 en WordPress (versiones ≤1.0.4) contiene una falla de validación de rutas que permite a atacantes no autenticados eliminar archivos arbitrarios del servidor. Esta vulnerabilidad puede escalarse a ejecución remota de código, comprometiendo sitios web de empresas en México y LATAM que utilicen este plugin. El riesgo es crítico especialmente en entornos de comercio electrónico y sitios corporativos expuestos a Internet.
The RapiSafe – Secure Multi File Upload for Contact Form 7 plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the handleAjaxRemoveUpload function in all versions up to, and including, 1.0.4. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). The nonce required to invoke the removal handler is exposed in public-facing JavaScript as RSMFCF7Vars.nonce on every Contact Form 7 page rendering a RapiSafe upload field, making it obtainable by any unauthenticated visitor.
