Low risk4th percentile - higher than 4% of all known CVEs
Summary
Electron is a framework for writing cross-platform desktop applications. Prior to 39.8.8, 40.9.0, 41.2.1, and 42.0.0-beta.3, the native autofill popup could be positioned by a cross-origin iframe outside that iframe's bounds, over the embedding page's UI, enabling clickjacking or spoofing of trusted UI. Apps are only affected if they embed untrusted content in iframes within windows that also display trusted UI. Apps that do not embed untrusted third-party content are not affected.
Risk Assessment
An attacker could exploit clickjacking or spoofing of trusted UI, potentially leading to unauthorized user actions or data theft.
Recommendation
Upgrade Electron to version 39.8.8, 40.9.0, 41.2.1, or 42.0.0-beta.3 or later. If your app embeds untrusted content, consider restricting its use.
