SCA: security update for github.com/siyuan-note/siyuan/kernel (GHSA-rx4h-526q-4458)
critical Tenable Self-Hosted Container Security Plugin ID 439550
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 version 3.6.2, an attacker who can place a
malicious URL in an Attribute View mAsse field can trigger stored XSS when a victim opens the Gallery or
Kanban view with “Cover From -> Asset Field” enabled. The vulnerable code accepts arbitrary http(s) URLs
without extensions as images, stores the attacker-controlled string in coverURL, and injects it directly
into an <img src="..."> attribute without escaping. In the Electron desktop client, the injected
JavaScript executes with nodeIntegration enabled and contextIsolation disabled, so the XSS reaches
arbitrary OS command execution under the victim’s account. This issue has been patched in version 3.6.2.
(CVE-2026-34448)
Solution
Update the github.com/siyuan-note/siyuan/kernel library and its related packages to version 3.6.2 or later.See Also
