Electron: Pointer lock permission requests can be attributed to the wrong frame

Collected exploitation and prediction evidence

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Published

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.

### Impact For `pointerLock` permission requests made from some cross-origin iframes, `session.setPermissionRequestHandler()` was given the top-level frame's `requestingUrl` and `isMainFrame` instead of the requesting frame's. Apps that grant pointer lock based on the requesting origin could grant it to embedded content under the top-level page's identity. Apps are only affected if they embed untrusted content in iframes and decide `pointerLock` requests by origin in `setPermissionRequestHandler`. Apps that do not embed untrusted content, or that deny `pointerLock` for it, are not affected. ### Workarounds Deny the `pointerLock` permission for web contents that embed untrusted frames. ### Fixed Versions * `45.0.0-alpha.13` * `44.5.0` * `43.7.6` * `42.11.9` ### For more information If you have any questions or comments about this advisory, email us at [[email protected]](mailto:[email protected])
