CyberRota Analysis
AI-GeneratedThe vulnerability affects Electron applications that utilize JavaScript, specifically those that accept object arguments from untrusted content without proper validation. This flaw can lead to prototype pollution attacks, potentially compromising the integrity of preload code even when context isolation is enabled. Developers of Electron applications should prioritize this update, especially if their code interacts with untrusted data.

Original NVD Description
Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 39.8.9, 40.9.2, 41.2.2, and 42.0.0-beta.4, objects copied across the contextBridge boundary from untrusted content could carry an attacker-influenced prototype, enabling prototype-pollution-style attacks against preload code despite context isolation being enabled. Apps are only affected if their preload code accepts object arguments from untrusted content and reads properties from them without own-property checks, while apps that only accept primitive arguments or validate object arguments are not affected. This issue is fixed in 39.8.9, 40.9.2, 41.2.2, and 42.0.0-beta.4.
