SCA: security update for electron (GHSA-hq2x-r82h-9wj4)

medium Tenable Self-Hosted Container Security Plugin ID 448465

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 41.10.4, 42.5.2, and 43.0.0, popups opened from a sandboxed iframe through Electron's
 OpenURLFromTab navigation path, including links using target="_blank" or a middle-click, did not receive
 the inherited HTML sandbox restrictions. An untrusted iframe using the allow-scripts allow-popups
 configuration could therefore open a popup with the embedding application's full origin, exposing that
 origin's cookies, storage, and same-origin scripting capabilities. Applications that do not embed
 untrusted content in sandboxed iframes are not affected. This issue is fixed in versions 41.10.4, 42.5.2,
 and 43.0.0. (CVE-2026-102673)

Solution

Update the electron library and its related packages to version 41.10.4 or later.
