SCA: security update for github.com/siyuan-note/siyuan/kernel (GHSA-phhp-9rm9-6gr2)

critical Tenable Cloud Security Plugin ID 440072

Description

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

 - SiYuan is a personal knowledge management system. Prior to 3.6.4, a malicious note synced to another user
 can trigger remote code execution in the SiYuan Electron desktop client. The root cause is that table
 caption content is stored without safe escaping and later unescaped into rendered HTML, creating a stored
 XSS sink. Because the desktop renderer runs with nodeIntegration enabled and contextIsolation disabled,
 attacker-controlled JavaScript executes with access to Node.js APIs. In practice, an attacker can import a
 crafted note into a synced workspace, wait for the victim to sync, and achieve code execution when the
 victim opens the note. This vulnerability is fixed in 3.6.4. (CVE-2026-39846)

Solution

Update the github.com/siyuan-note/siyuan/kernel library and its related packages to version 0.0.0-20260407035653-2f416e5253f1 or later.
