SiYuan has a SVG Sanitizer Bypass via `<animate>` Element — Unauthenticated XSS

SiYuan is a personal knowledge management system. Prior to 3.5.10, SiYuan's SVG sanitizer (SanitizeSVG) blocks dangerous elements (<script>, <iframe>, <foreignobject>) and removes on* event handlers and javascript: in href attributes. However, it does NOT block SVG animation elements (<animate>, <set>) which can dynamically set attributes to dangerous values at runtime, bypassing the static sanitization. This allows an attacker to inject executable JavaScript into the unauthenticated /api/icon/getDynamicIcon endpoint (type=8), creating a reflected XSS. This is a bypass of the fix for CVE-2026-29183 (fixed in v3.5.9). This vulnerability is fixed in v3.5.10.

SiYuan 跨站脚本漏洞

SiYuan是SiYuan开源的一个隐私至上的个人知识管理系统。 SiYuan 3.5.10之前版本存在跨站脚本漏洞，该漏洞源于SVG清理器未阻止SVG动画元素，可能绕过静态清理并导致反射型跨站脚本攻击。
