Summary

Electron versions before 42.11.3, from 43.0.0-alpha.1 before 43.7.0, from 44.0.0-alpha.1 before 44.3.0, and from 45.0.0-alpha.1 before 45.0.0-alpha.5 are affected. HID and USB permission checks made from an iframe cause setPermissionCheckHandler to receive the top-level frame's origin and details instead of the requesting frame's (CWE-346). An untrusted cross-origin iframe that the application delegated hid or usb to can therefore gain device access meant for the top-level page when the application uses origin-based logic.

Description from the CNA

Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 42.11.3, 43.7.0, 44.3.0, and 45.0.0-alpha.5, hid and usb permission checks made from an iframe caused setPermissionCheckHandler to receive the top-level frame's origin and details instead of the requesting frame's. An application that delegated hid or usb to a cross-origin untrusted iframe and allowed device access with origin-based logic could therefore grant that embedded frame access intended for the top-level page. This issue is fixed in versions 42.11.3, 43.7.0, 44.3.0, and 45.0.0-alpha.5.
