CVE-2026-113800Published

Electron: HID and USB permission checks can be attributed to the wrong origin

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 42.11.3, 43.7.0, 44.3.0, and 45.0.0-alpha.5, hid and usb permission checks made from an iframe caused setPermissionCheckHandler to receive the top-level frame's origin and details instead of the requesting frame's. An application that delegated hid or usb to a cross-origin untrusted iframe and allowed device access with origin-based logic could therefore grant that embedded frame access intended for the top-level page. This issue is fixed in versions 42.11.3, 43.7.0, 44.3.0, and 45.0.0-alpha.5.

### 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])
