CyberRota Analysis
AI-GeneratedThe vulnerability affects Electron applications that utilize the net.fetch() and net.request() methods, allowing remote servers to redirect requests to local resources, potentially disclosing sensitive file contents if the response body is exposed. This issue arises when applications make net requests to URLs controlled by attackers and follow HTTP redirects. Developers of Electron applications should prioritize updating to versions 39.8.8, 40.9.0, 41.2.1, or 42.0.0-beta.3 to mitigate the risk of local file disclosure.

Original NVD Description
Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 39.8.8, 40.9.0, 41.2.1, and 42.0.0-beta.3, when following HTTP redirects, net.fetch() and net.request() did not restrict which schemes a redirect could target. A remote server could redirect a request to a local resource, and if the app returns or forwards the response body, local file contents could be disclosed. Apps are only affected if they make net requests to attacker-influenced URLs with redirects followed and expose the response body. This issue is fixed in versions 39.8.8, 40.9.0, 41.2.1, and 42.0.0-beta.3.
