electron is vulnerable to Insufficient policy enforcement

Medium Risk
This Affects:
electronTL;DR
Electron enables AllowUniversalAccessFromFileURLs for renderers by default through the grant_file_protocol_extra_privileges fuse. In affected builds, Blink treated that preference as unconditional when assigning window agents, so http:, https:, and custom-scheme documents were routed to the universal-access agent instead of keeping their browser-provided AgentClusterKey. After Chromium moved cross-origin isolation state to the per-context agent cluster key, those pages no longer became cross-origin isolated even with correct COOP and COEP headers, breaking isolation-dependent capabilities such as SharedArrayBuffer. The patch constrains universal file access routing to file: origins only and restores expected agent assignment for other schemes.
