CVE-2026-56395

Name of the Vulnerable Software and Affected Versions SiYuan versions prior to 3.6.1

Description SiYuan fails to sanitize package metadata and README content within the Bazaar marketplace. This allows malicious authors to inject arbitrary HTML and JavaScript into the displayName, description, or README fields. Because the application is built on Electron with the nodeIntegration setting enabled, these Cross-Site Scripting (XSS) payloads can escape the browser context to execute operating system commands, leading to remote code execution on the device of any user browsing the marketplace.

Recommendations Update to version 3.6.1.
