      "value": "Spin is the developer tool for building and running serverless applications powered by WebAssembly. Prior to 2.4.3, some specifically configured Spin applications that use `self` requests without a specified URL authority can be induced to make requests to arbitrary hosts via the `Host` HTTP header. The following conditions need to be met for an application to be vulnerable: 1. The environment Spin is deployed in routes requests to the Spin runtime based on the request URL instead of the `Host` header, and leaves the `Host` header set to its original value; 2. The Spin application's component handling the incoming request is configured with an `allow_outbound_hosts` list containing `\"self\"`; and 3. In reaction to an incoming request, the component makes an outbound request whose URL doesn't include the hostname/port. Spin 2.4.3 has been released to fix this issue."

Antes de 2.4.3, algunas aplicaciones Spin configuradas espec\u00edficamente que usan solicitudes \"autom\u00e1ticas\" sin una autoridad de URL especificada pueden ser inducidas a realizar solicitudes a hosts arbitrarios a trav\u00e9s del encabezado HTTP \"Host\". Se deben cumplir las siguientes condiciones para que una aplicaci\u00f3n sea vulnerable: 1. El entorno Spin se implementa en rutas de solicitudes al tiempo de ejecuci\u00f3n de Spin seg\u00fan la URL de solicitud en lugar del encabezado \"Host\", y deja el encabezado \"Host\" configurado en su valor original; 2. El componente de la aplicaci\u00f3n Spin que maneja la solicitud entrante est\u00e1 configurado con una lista `allow_outbound_hosts` que contiene `\"self\"`; y 3. En reacci\u00f3n a una solicitud entrante, el componente realiza una solicitud saliente cuya URL no incluye el nombre de host/puerto. Se lanz\u00f3 Spin 2.4.3 para solucionar este problema."
