medium Tenable Cloud Security Plugin ID 436831

Description

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

- SiYuan is a personal knowledge management system. Versions prior to 3.5.4 are vulnerable to reflected
cross-site scripting in /api/icon/getDynamicIcon due to unsanitized SVG input. The endpoint generates SVG
images for text icons (type=8). The content query parameter is inserted directly into the SVG <text> tag
without XML escaping. Since the response Content-Type is image/svg+xml, injecting unescaped tags allows
breaking the XML structure and executing JavaScript. Version 3.5.4 patches the issue.] (CVE-2026-23847)
