CVE-2026-44586 Details
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.
A stored cross-site scripting vulnerability has been identified in the SiYuan desktop application, specifically in versions 2.1.12 prior to 3.7.0. This issue arises because the application’s Bazaar marketplace renders package author metadata from the public bazaar stage feed into HTML without proper escaping. In the desktop app, this unescaped data can be exploited to execute JavaScript, with access to Node.js APIs, allowing arbitrary code execution on the host machine.
Users should update to SiYuan version 3.7.0 or later, where this vulnerability has been fixed.
