SCA: security update for electron (GHSA-r5p7-gp4j-qhrx)

medium Tenable Cloud Security Plugin ID 439773

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, when an iframe requests fullscreen, pointerLock,
 keyboardLock, openExternal, or media permissions, the origin passed to
 session.setPermissionRequestHandler() was the top-level page's origin rather than the requesting iframe's
 origin. Apps that grant permissions based on the origin parameter or webContents.getURL() may
 inadvertently grant permissions to embedded third-party content. The correct requesting URL remains
 available via details.requestingUrl. Apps that already check details.requestingUrl are not affected. This
 issue has been patched in versions 38.8.6, 39.8.1, 40.8.1, and 41.0.0. (CVE-2026-34777)

Solution

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