      "value": "Caddy is an extensible server platform that uses TLS by default. From 2.4.0 until 2.11.3, the authorization layer and the /config traversal layer do not agree on what object the path refers to. In this case, a path authorized for one config object is accepted, but then resolves to a different config object during traversal. This happens because the authorization layer uses string prefix matching and the /config traversal layer parses array indices numerically using strconv.Atoi(). This vulnerability is fixed in 2.11.3."

      "value": "Caddy es una plataforma de servidor extensible que utiliza TLS por defecto. Desde la versión 2.4.0 hasta la 2.11.3, la capa de autorización y la capa de recorrido de /config no concuerdan sobre a qué objeto se refiere la ruta. En este caso, se acepta una ruta autorizada para un objeto de configuración, pero luego se resuelve a un objeto de configuración diferente durante el recorrido. Esto ocurre porque la capa de autorización utiliza la coincidencia de prefijos de cadena y la capa de recorrido de /config analiza los índices de matriz numéricamente usando strconv.Atoi(). Esta vulnerabilidad se corrige en la versión 2.11.3."
