CVE-2026-102676

CVE-2026-102676 · Electron: <webview> can enable Node.js integration in Web Workers despite embedder restrictions

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
