GHSA-fw47-9c62-h3vw CVE-2026-113800

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

Medium npm

Severity: 5.4 / 10; Medium · CVSS 3.1
Exploit chance (EPSS): 0.24%; Chance of exploitation in the next 30 days. Higher than 15.32% of scored vulnerabilities.
Known exploited: No; Not in CISA's catalog
Weakness: CWE-346 Origin Validation Error
Fix: 45.0.0-alpha.5; Upgrade electron to this version or later

Description

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

Affected versions

npm

Package	Vulnerable	Fixed in
electron	`>= 45.0.0-alpha.1, < 45.0.0-alpha.5`	`45.0.0-alpha.5`
electron	`>= 44.0.0-alpha.1, < 44.3.0`	`44.3.0`
electron	`>= 43.0.0-alpha.1, < 43.7.0`	`43.7.0`
electron	`< 42.11.3`	`42.11.3`

How to fix

Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

electron npm → `45.0.0-alpha.5`

npm

npm install electron@45.0.0-alpha.5
