Overview

electron is a framework which lets you write cross-platform desktop applications using JavaScript, HTML and CSS.

Affected versions of this package are vulnerable to Site Isolation Bypass. parent_execution_origin_ is provided from parent's RenderFrameHostImpl::last_committed_origin_ that is set during navigation commit. Worker creation IPC from the renderer to browser could race with navigation commit, and could see the wrong last committed origin.
