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&#8217;s **private** (non-public) playlist by passing its `id`. The Subsonic playlist `id` is `base64url(&#8220;\/.m3u&#8221;)`. 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&#8217;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.<\/p>\n<p>  Severity: 0.0 | NA<\/p>\n<p>  Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID :CVE-2026-49338 Published : June 19, 2026, 7:08 p.m. | 34\u00a0minutes ago Description :gonic is a music streaming server \/ free-software subsonic server API implementation.
