CVE-2026-100851

AzuraCast before 0.23.4 contains a code injection vulnerability in the ConfigWriter::cleanUpString() method that fails to sanitize Liquidsoap string interpolation sequences. Authenticated users with Media or Profile permissions can inject arbitrary Liquidsoap code into station configuration, leading to shell command execution as the azuracast user when the station restarts.

AzuraCast before 0.23.6 contains a code injection vulnerability in the remote relay password field due to incomplete migration from the vulnerable cleanUpString method to toRawString. Attackers with RemoteRelays station permission can inject nested Liquidsoap interpolation syntax to execute arbitrary code in the Liquidsoap process, disclose internal API keys, or disrupt station operation.

AzuraCast before 0.23.6 contains a missing permission check vulnerability in the GET /api/station/{station_id}/file/{id}/play endpoint that allows authenticated users to download media files from any station. Attackers can enumerate media files using sequential IDs and exfiltrate the complete media library of stations they lack permissions for.

AzuraCast before 0.23.6 lacks RequireInternalConnection middleware on the Liquidsoap API endpoint and incorrectly derives the AutoDJ flag from header presence rather than validated value. Users with View station permission can inject arbitrary now-playing metadata, disrupt live broadcasts, and disclose filesystem paths.

In AzuraCast before 0.23.8, the public On-Demand download endpoint fails to verify playlist-level access controls, allowing unauthenticated users to download media files excluded from On-Demand-enabled playlists. Attackers can bypass the station operator's intended access restrictions by directly requesting media via the download endpoint using valid media identifiers, exposing private or restricted audio content.

Command injection vulnerability in AzuraCast before 0.23.8 in Liquidsoap config generation for live recording, due to failure to quote streamer username in process.run calls.

AzuraCast before 0.23.8 contains a server-side request forgery and local file read vulnerability in the AutoDJ remote playlist fetch (getMediaFromRemoteUrl()). A user with Media permission can create a playlist with source=remote_url and remote_type=playlist pointing to a file:// path or internal HTTP endpoint. When AutoDJ builds the queue, the backend passes the URL directly to file_get_contents() with no scheme allowlist or private/loopback IP policy, allowing disclosure of host files (e.g., /etc/passwd or .env) and bodies of internal HTTP requests. No patched version was available at the time of publication.

AzuraCast before 0.23.8 contains an SSRF vulnerability in webhook URL validation. The validation only rejects link-local IP addresses, not loopback or private ranges, and non-IP hostnames bypass the check entirely. A user with WebHooks permission can configure a webhook to internal resources and trigger an HTTP POST with Now Playing data.

AzuraCast before 0.23.8 contains an SSRF vulnerability in Remote Relay URL validation. The validation only checks URL syntax and scheme, with no host or IP restrictions. A user with RemoteRelays permission can set a URL to loopback, private network, or cloud metadata addresses, and the automatic Now Playing sync will send requests to those addresses.

AzuraCast before 0.23.8 contains a DQL injection vulnerability in the sortOrder parameter in AbstractSearchableListAction.php. Attackers can inject arbitrary DQL expressions to extract sensitive database information, including user credentials and station settings.
