Electron: Malicious Device Can Be Selected by Untrusted App
GHSA-9899-m83m-qhpj
CVE-2026-34766
Summary
An Electron app may allow a device to be selected that doesn't meet the app's security filters. This is fixed in updated versions of Electron. To stay secure, update to Electron 41.0.0-beta.8, 40.7.0, 39.8.0, or 38.8.6.
What to do
- Update electron to version 38.8.6.
- Update electron to version 39.8.0.

Original title
Electron: USB device selection not validated against filtered device list
Original description
### Impact
The `select-usb-device` event callback did not validate the chosen device ID against the filtered list that was presented to the handler. An app whose handler could be influenced to select a device ID outside the filtered set would grant access to a device that did not match the renderer's requested `filters` or was listed in `exclusionFilters`.
The WebUSB security blocklist remained enforced regardless, so security-sensitive devices on the blocklist were not affected. The practical impact is limited to apps with unusual device-selection logic.
### Workarounds
There are no app side workarounds, you must update to a patched version of Electron.
### Fixed Versions
* `41.0.0-beta.8`
* `40.7.0`
* `39.8.0`
* `38.8.6`
