SCA: security update for electron (GHSA-f3pv-wv63-48x8)

high Tenable Self-Hosted Container Security Plugin ID 439964

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 39.8.5, 40.8.5, 41.1.0, and 42.0.0-alpha.5, when a renderer calls window.open() with a target
 name, Electron did not correctly scope the named-window lookup to the opener's browsing context group. A
 renderer could navigate an existing child window that was opened by a different, unrelated renderer if
 both used the same target name. If that existing child was created with more permissive webPreferences
 (via setWindowOpenHandler's overrideBrowserWindowOptions), content loaded by the second renderer inherits
 those permissions. Apps are only affected if they open multiple top-level windows with differing trust
 levels and use setWindowOpenHandler to grant child windows elevated webPreferences such as a privileged
 preload script. Apps that do not elevate child window privileges, or that use a single top-level window,
 are not affected. Apps that additionally grant nodeIntegration: true or sandbox: false to child windows
 (contrary to the security recommendations) may be exposed to arbitrary code execution. This vulnerability
 is fixed in 39.8.5, 40.8.5, 41.1.0, and 42.0.0-alpha.5. (CVE-2026-34765)

Solution

Update the electron library and its related packages to version 39.8.5 or later.
