SCA: security update for electron (GHSA-h7rp-cf8h-j98x)

high Tenable Cloud Security Plugin ID 445701

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 39.8.9, 40.9.2, 41.2.2, and 42.0.0-beta.5, apps that expose Promise-returning functions to web
 content via contextBridge may be vulnerable to a context isolation bypass. Untrusted web content could
 obtain access to the isolated preload world and, through it, every capability the preload script has. In
 renderers without a sandbox, or with nodeIntegration enabled, this may escalate to Node.js access. Apps
 are affected if they expose Promise-returning functions via contextBridge, the standard pattern for
 wrapping ipcRenderer.invoke, in windows that load untrusted content. This issue is fixed in versions
 39.8.9, 40.9.2, 41.2.2, and 42.0.0-beta.5. (CVE-2026-70601)

Solution

Update the electron library and its related packages to version 39.8.9 or later.
