## Description

Streambert is a cross-platform Electron Desktop App to stream and download video content. Versions prior to 2.5.0 contain an unvalidated auto-updater URL vulnerability that allows a compromised renderer process to make the main process download and execute an arbitrary binary, resulting in remote code execution. Version 2.5.0 contains a patch.
