Description : Koel is a free, open-source music streaming solution. Prior to 9.
- 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.
