Low risk21th percentile - higher than 21% of all known CVEs
Summary
In Electron prior to versions 38.8.6, 39.8.4, 40.8.4, and 41.0.0, the nodeIntegrationInWorker setting was not correctly scoped. In certain process-sharing scenarios, workers spawned in frames with nodeIntegrationInWorker: false could still receive Node.js integration. Only apps that enable nodeIntegrationInWorker are affected.
Risk Assessment
The organization may be exposed to unauthorized Node.js code execution in worker contexts, potentially leading to data leakage or privilege escalation in desktop applications.
Recommendation
Immediately update Electron to version 38.8.6, 39.8.4, 40.8.4, or 41.0.0. If not possible, disable nodeIntegrationInWorker.
Original NVD description (English source)
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.
