CVE-2026-56397 is a critical vulnerability in SiYuan before version 3.6.1 affecting the Bazaar marketplace. The application fails to properly sanitize package metadata and README content rendered from marketplace packages. A malicious package author can place arbitrary HTML and JavaScript into fields such as displayName, description, or README, resulting in stored cross-site scripting when another user browses the Bazaar. In the affected Electron-based application context, the injected script can leverage the enabled nodeIntegration setting to access Node.js capabilities and execute operating system commands, turning the XSS condition into remote code execution on the browsing user's host.
