SCA: security update for electron (GHSA-9pf5-hg6p-4pwp)

medium Tenable Cloud Security Plugin ID 445704

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS.
 Prior to 39.8.7, 40.9.0, 41.2.0, and 42.0.0-beta.1, serial-port and media permission checks made from an
 iframe passed the top-level frame origin to session.setPermissionCheckHandler instead of the requesting
 iframe origin. Origin-based handler logic could grant a cross-origin iframe device access intended only
 for the top-level origin. This issue is fixed in 39.8.7, 40.9.0, 41.2.0, and 42.0.0-beta.1.
 (CVE-2026-70599)
