      "value": "SiYuan is a personal knowledge management system. In versions 3.6.0 and below, the WebSocket endpoint (/ws) allows unauthenticated connections when specific URL parameters are provided (?app=siyuan\u0026id=auth\u0026type=auth). This bypass, intended for the login page to keep the kernel alive, allows any external client \u2014 including malicious websites via cross-origin WebSocket \u2014 to connect and receive all server push events in real-time. These events leak sensitive document metadata including document titles, notebook names, file paths, and all CRUD operations performed by authenticated users. Combined with the absence of Origin header validation, a malicious website can silently connect to a victim\u0027s local SiYuan instance and monitor their note-taking activity. This issue has been fixed in version 3.6.1."
