Context isolation bypass in Electron

Quick fix

GHSA-56pc-6jqp-xqj8 — electron: upgrade to the fixed version with the command below.

npm install electron@8.5.2

Details

### Impact Apps using both `contextIsolation` and `sandbox: true` are affected. Apps using both `contextIsolation` and `nativeWindowOpen: true` are affected.

This is a context isolation bypass, meaning that code running in the main world context in the renderer can reach into the isolated Electron context and perform privileged actions.

### Workarounds There are no app-side workarounds, you must update your Electron version to be protected.

### Fixed Versions * `11.0.0-beta.6` * `10.1.2` * `9.3.1` * `8.5.2`
