AzuraCast before 0.23.6 Missing Permission Check via /play

Noroxi assessment

Priority: Monitor (action score 28/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.20% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: AzuraCast AzuraCast 0.23.6.

Low priority for now. Upgrade to AzuraCast AzuraCast 0.23.6 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

AzuraCast before 0.23.6 contains a missing permission check vulnerability in the GET /api/station/{station_id}/file/{id}/play endpoint that allows authenticated users to download media files from any station. Attackers can enumerate media files using sequential IDs and exfiltrate the complete media library of stations they lack permissions for.
