electron is vulnerable to Insufficient Policy Enforcement
43
Medium Risk
This Affects:
electronTL;DR
electron's embedded Chromium service worker static router can accept invalid or opaque cache responses as cache sources. Crafted HTML that registers service workers with static routing can bypass intended same-origin isolation for cached fetches. Pre-fix versions allow cross-origin policy bypass through the cache source path. The backport blocks invalid responses and enables default CORP and opaque checks for static router cache sources.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and applications use service worker static routing.
