SCA: security update for go.senan.xyz/gonic (GHSA-2fp4-5v5c-4448)

high Tenable Cloud Security Plugin ID 444019

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. 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. (CVE-2026-49339)

Solution

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