CVE-2020-4075

In Electron before versions 7.2.4, 8.2.4, and 9.0.0-beta21, arbitrary local file read is possible by defining unsafe win

In Electron before versions 7.2.4, 8.2.4, and 9.0.0-beta21, arbitrary local file read is possible by defining unsafe window options on a child window opened via window.open. As a workaround, ensure you are calling event.preventDefault() on all new-window events where the url or options is not something you expect. This is fixed in versions 9.0.0-beta.21, 8.2.4 and 7.2.4.
