TL;DR

electron's embedded Chromium input stack accepts unvalidated mouse-capture requests from compromised renderer processes. After renderer compromise, crafted IPC can force mouse capture and leak cross-origin UI interaction data. Pre-fix builds allow cross-origin data exposure through the capture path. The backport validates SetMouseCapture requests in the browser process.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range.

Background info

electron is vulnerable to Improper Input Validation in versions 40.0.0 - 40.10.2 and 41.0.0 - 41.7.1.

How to fix this

Upgrade the electron library to the patch version.
