SCA: security update for electron (GHSA-p2rr-rvmm-c5fp)

medium Tenable Cloud Security Plugin ID 445705

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, requests to open external protocol URLs from web
 content did not take iframe sandbox restrictions into account, so a sandboxed iframe could cause an OS-
 registered external application to be launched. The frame sandbox state was also not made available to the
 app permission handlers, affecting apps that render untrusted content in sandboxed iframes and grant the
 openExternal permission by default when no setPermissionRequestHandler is installed. This issue is fixed
 in 39.8.8, 40.9.0, 41.2.1, and 42.0.0-beta.3. (CVE-2026-70612)

Solution

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