CVE-2026-34766
Description
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.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
