The vulnerability affects Electron framework versions prior to 39.8.7, 40.9.0, 41.2.0, and 42.0.0-beta.1, specifically in the handling of the mode option in the webContents.openDevTools() function. If exploited, an attacker could execute arbitrary scripts in the DevTools context, potentially gaining access to Node.js and compromising the application. Developers using affected versions of Electron should prioritize upgrading to the patched releases to mitigate this risk.

Original NVD Description

Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 39.8.7, 40.9.0, 41.2.0, and 42.0.0-beta.1, the mode option of webContents.openDevTools() was not sanitized before use by the DevTools frontend. If an attacker can influence this value, script under their control may run in the DevTools context, which in unsandboxed configurations has access to Node.js, including when untrusted input reaches the mode argument of openDevTools() or untrusted content calls openDevTools() on a webview it embeds. This issue is fixed in 39.8.7, 40.9.0, 41.2.0, and 42.0.0-beta.1.
