Description

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.

Affected products

• AzuraCast: before 0.23.8 — fixed in 0.23.8

How to fix

Upgrade to a fixed version: AzuraCast 0.23.8. Check the vendor advisory for mitigations.
