BrowserView window.open() Vulnerability Fix

· Одна мин. чтения

A code vulnerability has been discovered that allows Node to be re-enabled in child windows.

Opening a BrowserView with sandbox: true or nativeWindowOpen: true and nodeIntegration: false results in a webContents where window.open can be called and the newly opened child window will have nodeIntegration enabled. This vulnerability affects all supported versions of Electron.


We've published new versions of Electron which include fixes for this vulnerability: 2.0.17, 3.0.15, 3.1.3, 4.0.4, and 5.0.0-beta.2. We encourage all Electron developers to update their apps to the latest stable version immediately.

If for some reason you are unable to upgrade your Electron version, you can mitigate this issue by disabling all child web contents:

view.webContents.on('-add-new-contents', (e) => e.preventDefault());
