SCA: security update for electron (GHSA-4p4r-m79c-wq3v)

medium Tenable Cloud Security Plugin ID 439780

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, 39.8.3, 40.8.3, and 41.0.3, apps that register custom protocol handlers via
 protocol.handle() / protocol.registerSchemesAsPrivileged() or modify response headers via
 webRequest.onHeadersReceived may be vulnerable to HTTP response header injection if attacker-controlled
 input is reflected into a response header name or value. An attacker who can influence a header value may
 be able to inject additional response headers, affecting cookies, content security policy, or cross-origin
 access controls. Apps that do not reflect external input into response headers are not affected. This
 issue has been patched in versions 38.8.6, 39.8.3, 40.8.3, and 41.0.3. (CVE-2026-34767)

Solution

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