      "value": "Koel is a free, open-source music streaming solution. Prior to 9.7.1, App\\Helpers\\Network::isPublicHost() uses filter_var() with FILTER_FLAG_NO_PRIV_RANGE and FILTER_FLAG_NO_RES_RANGE, which treats NAT64 64:ff9b::/96 and 6to4 2002::/16 wrappers of private, loopback, or link-local IPv4 addresses as public. An authenticated user can place such an address in a podcast RSS <enclosure url> and reach app/Values/Podcast/EpisodePlayable.php through EpisodePlayable::createForEpisode(), where isSafeUrl() accepts the target and Http::sink($file)->get($url) fetches it. On a host with NAT64 or 6to4 routing, Koel can request internal services or cloud metadata and return the response body to the user. This issue is fixed in version 9.7.1"

Antes de la versión 9.7.1, App\\Helpers\\Network::isPublicHost() utiliza filter_var() con FILTER_FLAG_NO_PRIV_RANGE y FILTER_FLAG_NO_RES_RANGE, lo que trata los encapsulamientos NAT64 64:ff9b::/96 y 6to4 2002::/16 de direcciones IPv4 privadas, de bucle invertido o de enlace local como públicas. Un usuario autenticado puede colocar dicha dirección en una URL de [enclosure] de RSS de podcast y alcanzar app/Values/Podcast/EpisodePlayable.php a través de EpisodePlayable::createForEpisode(), donde isSafeUrl() acepta el objetivo y HTTP::sink($file)  ->  get($url) la obtiene.
