      "value": "Koel is a free, open-source music streaming solution. Prior to 9.7.0, the Subsonic-compatible createInternetRadioStation.view and updateInternetRadioStation.view routes accept an authenticated user's streamUrl without the SafeUrl and HasAudioContentType checks used by the regular radio API. app/Http/Requests/Subsonic/CreateInternetRadioStationRequest.php and app/Http/Requests/Subsonic/UpdateInternetRadioStationRequest.php pass the stored URL through app/Services/RadioService.php to app/Services/Radio/RadioStreamProxy.php, where RadioStreamProxy::openStream() calls fopen($url, 'r', false, $context). Streaming /radio/stream/{id} returns the upstream response body, allowing access to loopback, RFC1918, Docker bridge, metadata, or other internal HTTP services reachable from the Koel server. This issue is fixed in version 9.7.0."

La transmisión de /radio/stream/{id} devuelve el cuerpo de la respuesta ascendente, permitiendo el acceso a loopback, RFC1918, puente Docker, metadatos u otros servicios HTTP internos accesibles desde el servidor Koel.
