CVE-2026-56395 is a critical vulnerability in SiYuan before version 3.6.1 affecting the Bazaar marketplace. SiYuan fails to properly sanitize package metadata and README content rendered in Bazaar listings, specifically fields such as displayName, description, and README. A malicious package author can embed arbitrary HTML and JavaScript into those fields. When another user browses the Bazaar marketplace, the injected script executes in the Electron application context. Because the attack can leverage Electron's nodeIntegration setting, the XSS condition can be escalated from script execution in the UI to operating system command execution, resulting in remote code execution on the client system.
