CVE-2026-34766

Описание

Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 38.8.6, 39.8.0, 40.7.0, and 41.0.0-beta.8, 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. This issue has been patched in versions 38.8.6, 39.8.0, 40.7.0, and 41.0.0-beta.8.

A flaw was found in Electron. An attacker could influence an application's handler for the select-usb-device event to select a USB device ID outside of the filtered list. This could grant access to a USB device that was not intended by the application's security filters, potentially leading to unintended device interactions. The practical impact is limited to applications with unusual device-selection logic.
