SCA: security update for electron (GHSA-532v-xpq5-8h95)

high Tenable Cloud Security Plugin ID 439789

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 versions 39.8.1, 40.7.0, and 41.0.0, apps that use offscreen rendering and allow child windows
via window.open() may be vulnerable to a use-after-free. If the parent offscreen WebContents is destroyed
while a child window remains open, subsequent paint frames on the child dereference freed memory, which
may lead to a crash or memory corruption. Apps are only affected if they use offscreen rendering
(webPreferences.offscreen: true) and their setWindowOpenHandler permits child windows. Apps that do not
use offscreen rendering, or that deny child windows, are not affected. This issue has been patched in
versions 39.8.1, 40.7.0, and 41.0.0. (CVE-2026-34774)

Solution

Update the electron library and its related packages to version 39.8.1 or later.
