SCA: security update for github.com/siyuan-note/siyuan/kernel (GHSA-8q5w-mmxf-48jg)

medium Tenable Self-Hosted Container Security Plugin ID 440376

Description

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

 - SiYuan is an open-source personal knowledge management system. In versions 3.6.1 through 3.6.3, a prior
 fix for XSS in bazaar README rendering (incomplete fix for CVE-2026-33066) enabled the Lute HTML
 sanitizer, but the sanitizer does not block iframe tags, and its URL-prefix blocklist does not effectively
 filter srcdoc attributes which contain raw HTML rather than URLs. A malicious bazaar package author can
 include an iframe with a srcdoc attribute containing embedded scripts in their README. When other users
 view the package in SiYuan's marketplace UI, the payload executes in the Electron context with full
 application privileges, enabling arbitrary code execution on the user's machine. This issue has been fixed
 in version 3.6.4. (CVE-2026-40922)

Solution

Update the github.com/siyuan-note/siyuan/kernel library and its related packages to version 0.0.0-20260414013942-62eed37a3263 or later.
