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

Is GHSA-56pc-6jqp-xqj8 in any of your client repos?

Checking one package by hand is fine. Checking it across forty client projects is not. NPMscan reads the lockfiles in every GitHub repo you pick, finds each project with an affected electron, and gives you the command that fixes it.

Scan a project free, no signup Or connect GitHub to scan every repo
