SCA: security update for electron (GHSA-jfqg-hf23-qpw2)
medium Tenable Cloud Security Plugin ID 439774
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.
From versions 39.0.0-alpha.1 to before 39.8.0, 40.0.0-alpha.1 to before 40.7.0, and 41.0.0-alpha.1 to
before 41.0.0-beta.8, apps that pass VideoFrame objects (from the WebCodecs API) across the contextBridge
are vulnerable to a context isolation bypass. An attacker who can execute JavaScript in the main world
(for example, via XSS) can use a bridged VideoFrame to gain access to the isolated world, including any
Node.js APIs exposed to the preload script. Apps are only affected if a preload script returns, resolves,
or passes a VideoFrame object to the main world via contextBridge.exposeInMainWorld(). Apps that do not
bridge VideoFrame objects are not affected. This issue has been patched in versions 39.8.0, 40.7.0, and
41.0.0-beta.8. (CVE-2026-34780)
Solution
Update the electron library and its related packages to version 39.8.0 or later.See Also
