The maintainer's fix in  commit `6dd71e6a3c966867ef8c900d359a7df75789f410` added an ownership check based on `playlist.UserID`. However, `playlist.UserID` is derived from the first path segment of the attacker-controlled playlist ID, with no path containment on the resolved file path. Any authenticated Subsonic user can therefore bypass the ownership check and read any other user's playlist, delete any other user's playlist, and probe arbitrary file paths on the host for existence/readability. This is a bypass of the boundary the `6dd71e6` fix is trying to enforce; it is closely related to the original GONIC-1 IDOR but uses a different primitive (path traversal in the `id` parameter rather than direct cross-user access). Commit 0824bed88f6bbc490ba28bf09d28e5dfeb07b445 in version 0.21.0 fixes the issue.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-22","CWE-639"],"references":["https://github.com/sentriz/gonic/commit/0824bed88f6bbc490ba28bf09d28e5dfeb07b445","https://github.com/sentriz/gonic/commit/6dd71e6","https://github.com/sentriz/gonic/security/advisories/GHSA-2fp4-5v5c-4448","https://github.com/sentriz/gonic/security/advisories/GHSA-2fp4-5v5c-4448"],"products":[],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-49339","score":0.00388,"percentile":0.32635,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-2fp4-5v5c-4448","url":"https://osv.dev/vulnerability/GHSA-2fp4-5v5c-4448","summary":"gonic: Path Traversal in playlist `id` bypasses ownership check, enabling any user to read/delete other users' playlists","modified":"2026-07-07T16:11:10.052614945Z","packages":[{"ecosystem":"Go","name":"go.senan.xyz/gonic","purl":"pkg:golang/go.senan.xyz/gonic","ranges":["<0.21.0"],"fixed":["0.21.0"]}]},{"id":"GO-2026-5825","url":"https://osv.dev/vulnerability/GO-2026-5825","summary":"gonic: Path Traversal in playlist `id` bypasses ownership check, enabling any user to read/delete other users' playlists in go.senan.xyz/gonic","modified":"2026-07-07T16:00:21.468492496Z","packages":[{"ecosystem":"Go","name":"go.senan.xyz/gonic","purl":"pkg:golang/go.senan.xyz/gonic","ranges":["<0.21.0"],"fixed":["0.21.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
