SiYuan: Store XSS To Rce via Asset.render

Assigner: GitHub_M
Reserved: 07.07.2026 Published: 09.07.2026 Updated: 09.07.2026

SiYuan is an open-source personal knowledge management system. Prior to 3.7.1, Asset.render in app/src/asset/index.ts interpolates the unsanitized this.path value into HTML assigned to innerHTML, allowing a crafted asset link containing a double quote to break out of the src attribute, inject an event handler, and execute JavaScript that can run OS commands in the Electron renderer. This issue is fixed in versions 3.7.1-alpha.2 and 3.7.1.
