AI-suggested
Update Electron to one of the fixed versions: 42.11.3, 43.7.0, 44.3.0, or 45.0.0-alpha.5. This patch corrects the origin validation logic for HID and USB permission checks from iframes. No other mitigation is indicated by the vendor advisory.
Description
CVE-2026-113800 is an origin validation error in the Electron framework affecting versions prior to 42.11.3, 43.7.0, 44.3.0, and 45.0.0-alpha.5. The flaw causes permission checks for HID and USB devices made from an iframe to incorrectly use the top-level frame's origin instead of the requesting iframe's origin. This can allow a cross-origin untrusted iframe to gain device access intended only for the top-level page. The issue is fixed in the specified versions.
