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.","state":0,"publishedAt":"2026-06-19T19:16:36.687+00:00","modifiedAt":"2026-06-23T15:44:39.343+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","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/commit/0824bed88f6bbc490ba28bf09d28e5dfeb07b445","https://github.com/sentriz/gonic/commit/6dd71e6","https://github.com/sentriz/gonic/security/advisories/GHSA-2fp4-5v5c-4448"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-49339","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-22","CWE-639"],"productCriteria":[],"sourceDates":{"published":"2026-06-19T19:16:36.687","lastModified":"2026-06-23T15:44:39.343"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
