SCA: security update for github.com/siyuan-note/siyuan/kernel (GHSA-36v8-mpjm-8j5r)

critical Tenable Cloud Security Plugin ID 447658

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- SiYuan before v3.7.3 fails to apply publish-access filters to the getBacklinkDoc and getBackmentionDoc
content endpoints (/api/ref/getBacklinkDoc and /api/ref/getBackmentionDoc). While the corresponding
backlink list endpoints filter publish-forbidden documents, the content endpoints (gated only by
CheckAuth) do not. A publish-mode reader — including an anonymous reader when publish Basic Auth is
disabled — can call these endpoints directly with a publish-forbidden document's ID to retrieve its
rendered DOM content and to determine whether the document references a given block (a reference-existence
oracle). (CVE-2026-68586)

Solution

Update the github.com/siyuan-note/siyuan/kernel library and its related packages to version 0.0.0-20260721014413-f45749a7ef6e or later.
