title: IPC messages misrouted in Electron
description: The Electron framework lets you write cross-platform desktop applications using JavaScript, HTML and CSS. In affected versions of Electron IPC messages sent from the main process to a subframe in the renderer process, through webContents.sendToFrame, event.reply or when using the remote module, can in some cases be delivered to the wrong frame. If your app uses remote, calls webContents.sendToFrame, or calls event.reply in an IPC message handler then it is impacted by this issue. This has been fixed in versions 9.4.0, 10.2.0, 11.1.0, and 12.0.0-beta.9. There are no workarounds for this issue.
