Automated description summarized from trusted sources.

CVE-2026-102676 describes a vulnerability within the Electron framework, which is used for developing cross-platform desktop applications with JavaScript, HTML, and CSS. Prior to versions 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. This was possible even if the unsandboxed embedder had Node.js integration disabled, potentially allowing untrusted guest content to create a Node-enabled worker with elevated privileges beyond what the embedder intended. Applications that do not utilize the `<webview>` tag or those that maintain a sandboxed embedder are not affected by this issue. The vulnerability has been addressed in the specified Electron versions.

Description: 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.
