CVE-2022-29257

Electron's AutoUpdater module fails to validate certain nested components of the bundle

Description

Electron is a framework for writing cross-platform desktop applications using JavaScript (JS), HTML, and CSS. A vulnerability in versions prior to 18.0.0-beta.6, 17.2.0, 16.2.6, and 15.5.5 allows attackers who have control over a given apps update server / update storage to serve maliciously crafted update packages that pass the code signing validation check but contain malicious code in some components. This kind of attack would require significant privileges in a potential victim's own auto updating infrastructure and the ease of that attack entirely depends on the potential victim's infrastructure security. Electron versions 18.0.0-beta.6, 17.2.0, 16.2.6, and 15.5.5 contain a fix for this issue. There are no known workarounds.
