CVE-2026-102676
criticalElectron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS.
Vendor / product: Electronjs — electron
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 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 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.
