Context isolation bypass via contextBridge in Electron

Details

### Impact Apps using both `contextIsolation` and `contextBridge` 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 * `9.0.0-beta.21` * `8.2.4` * `7.2.4`
