CVE-2026-102676: Electron

High severity, CVSS 8.3. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Electron Electron: before 41.10.6 (fixed in 41.10.6); from 42.0.0-alpha.1, before 42.9.2 (fixed in 42.9.2); from 43.0.0-alpha.1, before 43.4.1 (fixed in 43.4.1); from 44.0.0-alpha.1, before 44.0.0-beta.5 (fixed in 44.0.0-beta.5)
