Vulnerability Title
SiYuan: Bazaar marketplace renders unescaped package author metadata, allowing XSS and Electron code execution
Source: NVD (National Vulnerability Database)
Vulnerability Description
SiYuan is an open-source personal knowledge management system. From 2.1.12 to before 3.7.0. SiYuan's Bazaar marketplace renders package author metadata from the public bazaar stage feed into HTML without escaping. In the desktop app this becomes stored XSS, and because SiYuan's Electron windows are created with nodeIntegration: true and contextIsolation: false, a successful payload can call Node.js APIs and execute code on the host. This vulnerability is fixed in 3.7.0.
