electron is vulnerable to Insufficient Policy Enforcement
43
Medium Risk
This Affects:
electronTL;DR
electron's embedded Chromium service worker static router does not consistently enforce Cross-Origin-Resource-Policy on cache-source responses. Crafted pages that drive static router cache lookups can read cross-origin data that should stay isolated. Pre-fix builds leak readable cross-origin bodies through the cache source. The backport enforces CORP requirements and rejects opaque responses 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.
