SCA: security update for github.com/siyuan-note/siyuan/kernel (GHSA-73g7-86qr-jrg3)

high Tenable Self-Hosted Container Security Plugin ID 439498

Description

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

 - SiYuan is a personal knowledge management system. From version 3.6.0 to before version 3.6.2, the
 SanitizeSVG function introduced in version 3.6.0 to fix XSS in the unauthenticated
 /api/icon/getDynamicIcon endpoint can be bypassed by using namespace-prefixed element names such as
 <x:script xmlns:x="http://www.w3.org/2000/svg">. The Go HTML5 parser records the element's tag as
 "x:script" rather than "script", so the tag check passes it through. The SVG is served with Content-Type:
 image/svg+xml and no Content Security Policy; when a browser opens the response directly, its XML parser
 resolves the prefix to the SVG namespace and executes the embedded script. This issue has been patched in
 version 3.6.2. (CVE-2026-34605)

Solution

Update the github.com/siyuan-note/siyuan/kernel library and its related packages to version 0.0.0-20260330031106-f09953afc57a or later.
