Authenticated OS command execution via unauthorized Liquidsoap configuration
Published Aug 24, 2026 · Updated Aug 24, 2026
Code injection in AzuraCast 0 through 0.23.8 allows remote authenticated users to execute OS commands through station profile edits. The profile edit endpoint deserializes backend_config under GROUP_GENERAL, and AbstractArrayEntity::fromArray() assigns custom_config fields without the Broadcasting permission check before ConfigWriter writes them verbatim into the Liquidsoap script. Station Profile permission and network access are sufficient; the built-in sync task restarts the backend and executes injected process.run() or process.exec() commands as the AzuraCast service account.
