CVE-2026-49340 - CERT CVE
ID CVE-2026-49340
Sažetak gonic is a music streaming server / free-software subsonic server API implementation. Prior to version 0.21.0, a logic error in `ServeCreateOrUpdatePlaylist` allows any authenticated Subsonic user (including non-admin) to write playlist M3U content to an attacker-controlled absolute filesystem path on the gonic host, and to create intermediate directories with `0o777` permissions. The bug is independent of CVE-2026-49338 and CVE-2026-49339. It is an unreachable guard clause combined with no path containment in `Store.Write`. Version 0.21.0 patches the issue.
