CVE-2026-100853 PUBLISHED

AzuraCast before 0.23.8 On-Demand Download Endpoint Authorization Bypass

Assigner: VulnCheck
Reserved: 27.09.2026 Published: 27.09.2026 Updated: 27.09.2026

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.
