Context isolation bypass via contextBridge in Electron

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.
