SCA: security update for electron (GHSA-3c8v-cfp5-9885)

medium Tenable Cloud Security Plugin ID 439776

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 versions 38.8.6, 39.8.1, 40.8.1, and 41.0.0, on macOS and Linux, apps that call
 app.requestSingleInstanceLock() were vulnerable to an out-of-bounds heap read when parsing a crafted
 second-instance message. Leaked memory could be delivered to the app's second-instance event handler. This
 issue is limited to processes running as the same user as the Electron app. Apps that do not call
 app.requestSingleInstanceLock() are not affected. Windows is not affected by this issue. This issue has
 been patched in versions 38.8.6, 39.8.1, 40.8.1, and 41.0.0. (CVE-2026-34776)

Solution

Update the electron library and its related packages to version 38.8.6 or later.
