CVE-2026-76836
AzuraCast through 0.23.8 Liquidsoap Configuration Write via Profile Edit Serialization Group Bypass
Description

AzuraCast exposes the Liquidsoap custom configuration fields through an endpoint that does not require the permission guarding them. The backend_config property in backend/src/Entity/Station.php is annotated with GROUP_GENERAL, and PUT /api/station/{station_id}/profile/edit in backend/src/Controller/Api/Stations/ProfileEditController.php deserializes with that group while requiring only StationPermissions::Profile. AbstractArrayEntity::fromArray() then assigns every public property with no field-level permission check, so custom_config_top, custom_config, custom_config_pre_playlists, custom_config_pre_live, custom_config_pre_fade and custom_config_bottom are writable through it. ConfigWriter::writeCustomConfigurationSection() emits those values verbatim into the generated Liquidsoap .liq script, where the process.run() and process.exec() built-ins execute operating system commands when the backend restarts, which the built-in sync task triggers automatically once needs_restart is set. The dedicated endpoint for the same data, PUT /api/station/{id}/liquidsoap-config, requires StationPermissions::Broadcasting, so a station manager holding only the profile permission reaches configuration that the intended boundary reserves for broadcasting operators.

Solution
Enforce proper authorization checks for station profile editing to prevent privilege escalation.
  • Restrict access to profile editing API endpoint.
  • Require appropriate permissions for editing Liquidsoap config.
  • Validate all user inputs to prevent command injection.
  • Update software to patch access control vulnerabilities.
