Summary

Electron versions before 42.11.9, from 43.0.0-alpha.1 before 43.7.6, from 44.0.0-alpha.1 before 44.5.0, and from 45.0.0-alpha.1 before 45.0.0-alpha.13 are affected. An origin validation error (CWE-346) causes some cross-origin iframe pointerLock requests to report the top-level page's requestingUrl and isMainFrame values in session.setPermissionRequestHandler(). An application that embeds untrusted iframe content and grants pointer lock based on the requesting origin could grant the permission under the top-level page's identity. Applications that deny pointerLock for untrusted embedded content are not affected.

Description from the CNA

Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 42.11.9, 43.7.6, 44.5.0, and 45.0.0-alpha.13, pointerLock permission requests from some cross-origin iframes caused session.setPermissionRequestHandler() to receive the top-level frame's requestingUrl and isMainFrame values instead of those of the requesting frame. An application that embeds untrusted iframe content and grants pointer lock based on the requesting origin could therefore grant the permission under the top-level page's identity. Applications that deny pointerLock for untrusted embedded content are not affected. This issue is fixed in versions 42.11.9, 43.7.6, 44.5.0, and 45.0.0-alpha.13.
