CVE-2026-34775: Electronjs Electron

Critical severity, CVSS 9.8. EPSS: 0.4% 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 versions 38.8.6, 39.8.4, 40.8.4, and 41.0.0, the nodeIntegrationInWorker webPreference was not correctly scoped in all configurations. In certain process-sharing scenarios, workers spawned in frames configured with nodeIntegrationInWorker: false could still receive Node.js integration. Apps are only affected if they enable nodeIntegrationInWorker. Apps that do not use nodeIntegrationInWorker are not affected. This issue has been patched in versions 38.8.6, 39.8.4, 40.8.4, and 41.0.0.

Affected products

• Electronjs Electron: before 38.8.6 (fixed in 38.8.6); from 39.0.0, before 39.8.4 (fixed in 39.8.4); from 40.0.0, before 40.8.4 (fixed in 40.8.4); version 41.0.0 only
