SCA: security update for electron (GHSA-9f4c-93c8-jc8g)

high Tenable Cloud Security Plugin ID 445692

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 39.8.10, 41.10.3, and 42.0.1, a sandboxed iframe without the allow-popups keyword could still
 open a new window or trigger setWindowOpenHandler with no user interaction because new-window navigations
 taking the OpenURL path did not apply the iframe sandbox popup restriction. Apps that embed untrusted
 content in sandboxed iframes and rely on the absence of allow-popups to prevent window creation are
 affected, while apps that deny window creation in setWindowOpenHandler or do not embed untrusted content
 in sandboxed iframes are not affected. This issue is fixed in 39.8.10, 41.10.3, and 42.0.1.
 (CVE-2026-70608)

Solution

Update the electron library and its related packages to version 39.8.10 or later.
