Overview
org.webjars.npm: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 Improper Isolation or Compartmentalization in the handling of the nodeIntegrationInWorker configuration in shared renderer processes. An attacker can gain unauthorized access to Node.js integration by exploiting process-sharing scenarios where workers in frames configured with nodeIntegrationInWorker: false still receive Node.js integration.
Note:
This is only exploitable if nodeIntegrationInWorker is enabled in applications that also open child windows or embed content with differing webPreferences.
Workaround
This vulnerability can be mitigated by avoiding the enabling of nodeIntegrationInWorker in applications that open child windows or embed content with different webPreferences.
