A high-severity flaw in Electron (CVE-2026-70608) allowed sandboxed iframes to bypass the `allow-popups` sandbox restriction through the internal OpenURL navigation path, letting malicious or compromised embedded content spawn unauthorized popup windows. The fix upgrades Electron from 40.10.6 to 41.10.3 (also patched in 42.0.1 and 39.8.10), closing the navigation-layer gap without requiring any application code changes.
