Music Assistant lets attackers run code via playlist API

CVE-2026-26975 · published 8 months ago
Summary

The Music Assistant media manager (versions up to 2.6.3) lets anyone on the same network change files anywhere on the server through its playlist update function. By placing a malicious file in a Python library folder, an attacker can make the system run whatever commands they choose. Upgrade to version 2.7.0 or later to stop this risk.

Original advisory text
Music Assistant Server Path Traversal in Playlist Update API Allows Remote Code Execution
Music Assistant is an open-source media library manager that integrates streaming services with connected speakers. Versions 2.6.3 and below allow unauthenticated network-adjacent attackers to execute arbitrary code on affected installations. The music/playlists/update API allows users to bypass the .m3u extension enforcement and write files anywhere on the filesystem, which is exacerbated by the container running as root. This can be exploited to achieve Remote Code Execution by writing a malicious .pth file to the Python site-packages directory, which will execute arbitrary commands when Python loads. This issue has been fixed in version 2.7.0.
