Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 41.10.6, 42.9.2, 43.4.1, and 44.0.0-beta.5, an Electron <webview> guest could enable nodeIntegrationInWorker for its Web Workers even when the unsandboxed embedder had Node.js integration disabled, allowing untrusted guest content to create a Node-enabled worker with more privilege than the embedder granted. Applications that do not enable the <webview> tag or that keep the embedder sandboxed are not affected. This issue is fixed in versions 41.10.6, 42.9.2, 43.4.1, and 44.0.0-beta.5.

 https://vulnerability.circl.lu/vuln/ghsa-9qh4-3jw8-366w GHSA-9qh4-3jw8-366w — Electron: <webview> can enable Node.js integration in Web Workers despite embedder restrictions 2026-10-01T15:45:30.893266+00:00

Affected: npm: electron

### Impact

A `<webview>` could enable Node.js integration in its Web Workers even when its embedder had Node.js integration disabled, giving guest content more privilege than the embedder allowed.

Apps are only affected if they enable the `<webview>` tag and the embedder is unsandboxed. Apps that do not use `<webview>`, or that keep the embedder sandboxed, are not affected.

### Workarounds

Remove `nodeIntegrationInWorker` from the guest preferences in a `will-attach-webview` handler, or do not enable the `<webview>` tag when loading untrusted content.

### Fixed Versions

* `44.0.0-beta.5` * `43.4.1` * `42.9.2` * `41.10.6`
