CVE-2026-26975

HIGH

Music Assistant <=2.6.3 - RCE

Title source: llm
STIX 2.1

Description

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.
