CVE-2026-121429: AzuraCast command injection in StereoTool configuration

CVE-2026-121429 · Severity: high · CVSS 8.8 · Published 2026-11-03

AzuraCast is a web-based radio automation platform. A vulnerability in its StereoTool audio processing feature allows station users with Profile permission to inject shell commands into configuration parameters, leading to arbitrary code execution on the container when the station restarts. An attacker could read or modify sensitive data, including media files and credentials stored in the system.

Technical details

A command injection vulnerability in ConfigWriter.php allows attacker-controlled input from stereo_tool_configuration_path and stereo_tool_license_key fields to be concatenated directly into a shell command without proper escaping, then passed to Liquidsoap's pipe() operator which invokes /bin/sh -c. The toRawString() wrapper prevents Liquidsoap-level interpolation but does not escape shell metacharacters. Exploitation requires StationPermissions::Profile (not admin-only) and StereoTool binary to be installed; code execution occurs as the Liquidsoap process user on station start/restart.
