The handler ignores event.sender and forwards any received payload to every BrowserWindow returned by BrowserWindow.getAllWindows(), including windows belonging to other opened workspaces. A renderer connected to an attacker-controlled remote kernel can therefore send {cmd: &#34;lockscreenByMode&#34;} and have it delivered across the workspace boundary; a sibling workspace window whose lockScreenMode is set to 1 invokes lockScreen(). Repeated messages allow the remote workspace to repeatedly lock unrelated local workspace windows, causing a limited denial of service. No confidentiality, integrity, or code-execution impact was observed.</p> <p>SiYuan before v3.8.4 does not validate the sender or restrict recipients in the &#39;siyuan-send-windows&#39; IPC handler of the Electron main process (app/electron/main.js).
