CVE-2026-113800

### Impact For `hid` and `usb` permission checks made from an iframe, `session.setPermissionCheckHandler` was given the top-level frame's origin and details instead of the requesting frame's. Apps that allow these permissions based on origin could grant an embedded frame access intended for the top-level page. You're only affected if you use `setPermissionCheckHandler` with origin-based logic for `hid` or `usb` and embed cross-origin iframes with `allow="hid"` or `allow="usb"`. Apps that don't delegate those features to untrusted iframes are not affected. ### Workarounds Don't add `allow="hid"` / `allow="usb"` to untrusted iframes, or make the decision in your `select-hid-device` / `select-usb-device` handler using `details.frame`. ### Fixed Versions * `45.0.0-alpha.5` * `44.3.0` * `43.7.0` * `42.11.3` ### For more information If you have any questions or comments about this advisory, email us at [[email protected]](mailto:[email protected])
