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

Electron mis-attributes pointer lock permission requests from some cross-origin iframes to the top-level page's origin and main-frame flag. An embedded untrusted frame can be granted pointer lock under the top-level page's identity by apps that decide permissions by origin.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- npm:electron affected >= 45.0.0-alpha.1, < 45.0.0-alpha.13 fixed 45.0.0-alpha.13
- npm:electron affected >= 44.0.0-alpha.1, < 44.5.0 fixed 44.5.0
- npm:electron affected >= 43.0.0-alpha.1, < 43.7.6 fixed 43.7.6
- npm:electron affected < 42.11.9 fixed 42.11.9

## How to check

Check whether your app's session.setPermissionRequestHandler grants 'pointerLock' based on requestingUrl or isMainFrame, and whether your pages embed untrusted iframes.
Run: npm ls electron

## Fix

Upgrade electron to 45.0.0-alpha.13, 44.5.0, 43.7.6, or 42.11.9 (match your major line).
Workaround until upgraded: deny the pointerLock permission for web contents that embed untrusted frames.

## From the sources

### 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`
