      "value": "Koel is a free, open-source music streaming solution. Prior to 9.7.1, outbound podcast and radio fetch paths perform a point-in-time App\\Helpers\\Network::isPublicHost() or isSafeUrl() check without pinning the validated address, and most paths lack redirect-hop validation and do not revalidate every redirect target. PhanAn\\Poddle\\Poddle::fromUrl(), PodcastService::getStreamableUrl(), PodcastService::isPodcastObsolete(), App\\Rules\\HasAudioContentType, and App\\Rules\\SafeUrl can therefore follow an attacker-controlled redirect to an internal address or connect after DNS rebinding changes a public resolution to a private one. These paths are reachable through podcast and radio APIs, including createPodcastChannel, createInternetRadioStation, refreshPodcasts, apiResource podcasts, and radio/stations, allowing an authenticated user to request internal services or cloud metadata and potentially receive parsed or streamed response content. This issue is fixed in version 9.7.1."

      "value": "Koel es una solución de transmisión de música gratuita y de código abierto. Antes de la versión 9.7.1, las rutas de recuperación de podcasts y radio salientes realizan una verificación puntual de App\\Helpers\\Network::isPublicHost() o isSafeUrl() sin fijar la dirección validada, y la mayoría de las rutas carecen de validación de salto de redirección y no revalidan cada objetivo de redirección. PhanAn\\Poddle\\Poddle::fromUrl(), PodcastService::getStreamableUrl(), PodcastService::isPodcastObsolete(), App\\Rules\\HasAudioContentType y App\\Rules\\SafeUrl pueden, por lo tanto, seguir una redirección controlada por el atacante a una dirección interna o conectarse después de que el DNS rebinding cambie una resolución pública a una privada. Estas rutas son accesibles a través de las API de podcasts y radio, incluyendo createPodcastChannel, createInternetRadioStation, refreshPodcasts, apiResource podcasts y radio/stations, lo que permite a un usuario autenticado solicitar servicios internos o metadatos de la nube y potencialmente recibir contenido de respuesta analizado o transmitido. Este problema se ha solucionado en la versión 9.7.1."
