CVE-2026-41936

Vvveb before version 1.0.8.2 contains an XML external entity (XXE) injection vulnerability in the admin Tools/Import feature that allows authenticated site_admin users to read arbitrary files and modify database records. Attackers can exploit the XML parser configuration in system/import/xml.php to inject file:// or php://filter entity references that are resolved and persisted into the application database, enabling arbitrary file disclosure and administrator password hash overwriting for privilege escalation.

Summary		(es) Vvveb anterior a la versión 1.0.8.2 contiene una vulnerabilidad de inyección de entidad externa XML (XXE) en la función Herramientas/Importar del administrador que permite a los usuarios site_admin autenticados leer archivos arbitrarios y modificar registros de la base de datos. Los atacantes pueden explotar la configuración del analizador XML en system/import/xml.php para inyectar referencias de entidad file: // o php://filter que se resuelven y persisten en la base de datos de la aplicación, lo que permite la divulgación arbitraria de archivos y la sobrescritura de hashes de contraseñas de administrador para la escalada de privilegios.
