      "value": "The Betheme theme for WordPress is vulnerable to Arbitrary File Upload in versions up to, and including, 28.4. This is due to the upload_icons() function workflow moving and unzipping user-controlled ZIP files into a public uploads directory without validating extracted file types. This makes it possible for authenticated attackers, with author-level access and above, to upload arbitrary files (including PHP) and achieve remote code execution via the Icons icon-pack upload flow."

      "lang": "es",
      "value": "El tema Betheme para WordPress es vulnerable a la Carga Arbitraria de Archivos en versiones hasta la 28.4, inclusive. Esto se debe a que el flujo de trabajo de la función upload_icons() mueve y descomprime archivos ZIP controlados por el usuario en un directorio público de cargas sin validar los tipos de archivos extraídos. Esto permite a atacantes autenticados, con acceso de nivel de autor y superior, cargar archivos arbitrarios (incluido PHP) y lograr ejecución remota de código a través del flujo de carga de paquetes de iconos de Icons."
