{"apiVersion":"1.0","identifier":"CVE-2026-76836","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.","publishedAt":"2026-08-24T18:17:21","lastModifiedAt":"2026-08-24T20:17:20","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-76836","cvssScore":8.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00331,"riskScore":0.91,"affectedProduct":"AzuraCast","affectedVersions":"unknown","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-76836","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-76836","en":"https://www.redsauce.net/en/cves/CVE-2026-76836","fr":"https://www.redsauce.net/fr/cves/CVE-2026-76836","pt":"https://www.redsauce.net/pt/cves/CVE-2026-76836","de":"https://www.redsauce.net/de/cves/CVE-2026-76836","sk":"https://www.redsauce.net/sk/cves/CVE-2026-76836","el":"https://www.redsauce.net/el/cves/CVE-2026-76836"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-76836"}}
