Arbitrary file read via window-open IPC in Electron

Details

### Impact The vulnerability allows arbitrary local file read by defining unsafe window options on a child window opened via window.open.

### Workarounds Ensure you are calling `event.preventDefault()` on all [`new-window`](https://electronjs.org/docs/api/web-contents#event-new-window) events where the `url` or `options` is not something you expect.

### Fixed Versions * `9.0.0-beta.21` * `8.2.4` * `7.2.4`
