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

Noroxi assessment

Priority: Monitor (action score 34/100)

  • 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: 0.41% (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.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
