SCA: security update for github.com/siyuan-note/siyuan/kernel (GHSA-6865-qjcf-286f)

medium Tenable Cloud Security Plugin ID 438338

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 3.5.9, an unauthenticated reflected XSS
 vulnerability exists in the dynamic icon API endpoint "GET /api/icon/getDynamicIcon" when type=8,
 attacker-controlled content is embedded into SVG output without escaping. Because the endpoint is
 unauthenticated and returns image/svg+xml, a crafted URL can inject executable SVG/HTML event handlers
 (for example onerror) and run JavaScript in the SiYuan web origin. This can be chained to perform
 authenticated API actions and exfiltrate sensitive data when a logged-in user opens the malicious link.
 This issue has been patched in version 3.5.9. (CVE-2026-29183)
