Description

Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 39.8.7, 40.9.0, 41.2.0, and 42.0.0-beta.1, serial-port and media permission checks made from an iframe passed the top-level frame origin to session.setPermissionCheckHandler instead of the requesting iframe origin. Origin-based handler logic could grant a cross-origin iframe device access intended only for the top-level origin. This issue is fixed in 39.8.7, 40.9.0, 41.2.0, and 42.0.0-beta.1.
