Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

AzuraCast 通过一个无需权限验证的 API 端点，暴露了 Liquidsoap 自定义配置字段。具体而言， 中的 属性被标注为 组，而 中的 接口在使用该组进行反序列化时，仅需持有 权限即可。 随后， 方法会将所有公共属性直接赋值，且未执行任何字段级别的权限检查。这导致 、 、 、 、 和 等字段可通过此接口被写入。 当后端重启时， 方法会将这些值原样写入生成的 Liquidsoap 脚本中。由于该脚本内置了 和 函数，一旦执行即可运行操作系统命令。而后端内置的同步任务会在 标志位被设置后自动触发重启，从而

Vulnerability Title
AzuraCast through 0.23.8 Liquidsoap Configuration Write via Profile Edit Serialization Group Bypass
Source: CVE Program / CVE List V5
Vulnerability 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.
