How to fix?

Upgrade electron to version 2.0.17, 3.0.15, 3.1.3, 4.0.4, 5.0.0-beta.2 or higher.

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());

Overview

electron is a framework which lets you write cross-platform desktop applications using JavaScript, HTML and CSS.

Affected versions of this package are vulnerable to Arbitrary Code Execution. 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 will have nodeIntegration enabled.
