CVE-2026-44670
Overview
CVE-2026-44670 is a known-severity vulnerability. It was published on May 14, 2026.
Technical Description
SiYuan is an open-source personal knowledge management system. Prior to 3.7.0, the kernel stores Attribute View (AV / database) names without any HTML escape, then a render template uses raw strings.ReplaceAll(tpl, "${avName}", nodeAvName) to embed the name in HTML before pushing to all clients via WebSocket. Three independent client paths (render.ts:120 → outerHTML, Title.ts:401 → innerHTML, transaction.ts:559 → innerHTML) consume the value without escaping. Because the main BrowserWindow runs nodeIntegration:true, contextIsolation:false, webSecurity:false (app/electron/main.js:407-411), HTML injection in the renderer becomes Node.js code execution. This vulnerability is fixed in 3.7.0.
