SCA: security update for go.senan.xyz/gonic (GHSA-hmgp-w9jm-vp95)

high Tenable Cloud Security Plugin ID 444018

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, the Subsonic API endpoints `/rest/deletePlaylist.view` and `/rest/getPlaylist.view` perform no
 per-resource authorization. Once authenticated as any user (admin or not), an attacker can delete any
 playlist owned by any other user (including admin) by passing its `id` and read the full contents (name,
 comment, song list) of any other user's **private** (non-public) playlist by passing its `id`. The
 Subsonic playlist `id` is `base64url("<userID>/<filename>.m3u")`. Because filenames are user-supplied or
 time-derived and the `userID` is a small integer, IDs are guessable and frequently exposed (e.g. a
 previously-public playlist that was later made private still has the same ID). This breaks the multi-user
 trust boundary of gonic: a low-privileged user can wipe an administrator's curated playlists, and a user
 can exfiltrate any private playlist they obtain an ID for. The issue was fixed in commit
 `6dd71e6a3c966867ef8c900d359a7df75789f410`, which is part of version 0.21.0. (CVE-2026-49338)

Solution

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