high Tenable Cloud Security Plugin ID 444021

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-49340)

Solution

Update the go.senan.xyz/gonic library and its related packages to version 0.21.0 or later.
