Published

SiYuan through 3.8.4 renders notebook names as raw HTML in the Daily Note picker dialog without escaping, allowing stored cross-site scripting in the Electron renderer. Attackers can create notebooks with HTML payloads in names that execute JavaScript with Node.js access when the picker opens, enabling operating system command execution.
