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.","state":0,"publishedAt":"2026-06-19T19:08:34.22+00:00","modifiedAt":"2026-06-23T02:21:47.053+00:00","affected":[{"ecosystem":"Vendor product","name":"gonic","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"sentriz\",\n                    \"product\": \"gonic\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.21.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N","score":7.1,"severity":"HIGH"}],"references":["https://github.com/sentriz/gonic/security/advisories/GHSA-hmgp-w9jm-vp95","https://github.com/sentriz/gonic/commit/6dd71e6"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-49338","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-49338","identifiers":["CVE-2026-49338"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
