Vulnerabilidad · Publicado 16/08/2026
El plugin ProSolution WP Client para WordPress (versiones ≤2.0.8) contiene una falla de validación de rutas que permite a atacantes no autenticados eliminar archivos arbitrarios del servidor. Esta vulnerabilidad puede ser explotada para ejecutar código remoto eliminando archivos críticos de WordPress, comprometiendo completamente el sitio web. Afecta directamente a pequeñas y medianas empresas en LATAM que utilizan este plugin en plataformas de comercio electrónico y gestión de contenidos.
The ProSolution WP Client plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the proSol_fileDeleteProcess function in all versions up to, and including, 2.0.8. 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). An attacker must first call the proSol_fileUploadModalProcess handler to poison their own session with a path-traversal key, then call proSol_fileDeleteProcess with that key as the filename parameter; both steps require only the publicly exposed frontend nonce.
