VulnerabilityCVE-2026-113800

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

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.

What happened

### 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`

About this data

This record was ingested from a data source. Retrieved: Oct 26, 2026, 19:40 UTC. Ingestion is not an independent editorial investigation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.
