electron is vulnerable to Origin Validation Error
65
Medium Risk
This Affects:
electronTL;DR
Custom protocol handlers registered with fetch API support could accidentally bypass cross-origin controls because scheme loaders skipped the standard CORS gate and exposed readable bodies where only opaque responses were intended. Installer paths could resolve inconsistently across Squirrel stages and mishandle symlink-heavy layouts. Sandbox navigation and offscreen rendering paths received tighter enforcement and bounds checks to reduce bypass and out-of-bounds read classes. Graphics and GPU command-buffer validation plus Skia-related hardening closes integer-trim hazards from upstream rendering code.
