CVE-2026-100853: Missing authorization vulnerability

In AzuraCast before 0.23.8, the public On-Demand download endpoint fails to verify playlist-level access controls, allowing unauthenticated users to download media files excluded from On-Demand-enabled playlists. Attackers can bypass the station operator's intended access restrictions by directly requesting media via the download endpoint using valid media identifiers, exposing private or restricted audio content.
