Opis źródłowy (NVD)

SiYuan is a personal knowledge management system. In versions 3.6.0 and below, the mobile file tree (MobileFiles.ts) renders notebook names via innerHTML without HTML escaping when processing renamenotebook WebSocket events. The desktop version (Files.ts) properly uses escapeHtml() for the same operation. An authenticated user who can rename notebooks can inject arbitrary HTML/JavaScript that executes on any mobile client viewing the file tree. Since Electron is configured with nodeIntegration: true and contextIsolation: false, the injected JavaScript has full Node.js access, escalating stored XSS to full remote code execution. The mobile layout is also used in the Electron desktop app when the window is narrow, making this exploitable on desktop as well. This issue has been fixed in version 3.6.1.
