SCA: security update for electron (GHSA-4f78-qhmw-8j8m)

medium Tenable Self-Hosted Container Security Plugin ID 445702

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 39.8.7, 40.9.0, 41.2.0, and 42.0.0-beta.1, the mode option of webContents.openDevTools() was not
sanitized before use by the DevTools frontend. If an attacker can influence this value, script under their
control may run in the DevTools context, which in unsandboxed configurations has access to Node.js,
including when untrusted input reaches the mode argument of openDevTools() or untrusted content calls
openDevTools() on a webview it embeds. This issue is fixed in 39.8.7, 40.9.0, 41.2.0, and 42.0.0-beta.1.
(CVE-2026-70609)

Update the electron library and its related packages to version 39.8.7 or later.
