SCA: security update for electron (GHSA-m55f-7gqj-fr98)

medium Tenable Self-Hosted Container Security Plugin ID 445696

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 39.8.8, 40.9.0, 41.2.1, and 42.0.0-beta.3, extension tab and scripting APIs were not scoped to
the extension's own session. A malicious or compromised extension loaded into one session could navigate,
script, and read from windows belonging to a different session. Apps are only affected if they load Chrome
extensions via session.loadExtension and rely on separate sessions to isolate that extension from other
content. This issue is fixed in versions 39.8.8, 40.9.0, 41.2.1, and 42.0.0-beta.3. (CVE-2026-70602)

Solution

Update the electron library and its related packages to version 39.8.8 or later.
