Name of the Vulnerable Software and Affected Versions Music Assistant versions 2.6.3 and below

Description Music Assistant, an open-source media library manager, is susceptible to unauthenticated remote code execution from network-adjacent attackers. The issue stems from a bypass of the .m3u extension enforcement within the

/music/playlists/update

API endpoint, allowing attackers to write files to arbitrary locations on the filesystem. The application runs as root, exacerbating the impact. Exploitation involves writing a malicious .pth file to the Python site-packages directory, leading to arbitrary command execution upon Python loading. The

update

API endpoint and the

.pth

file are key components in the exploitation process.

Recommendations Update to version 2.7.0 or later.
