Security researchers have identified several vulnerabilities in how apps open and handle URLs. Attackers can manipulate URLs in such a way that allows them to run code on the targeted device. Researchers looked at multiple operating systems and popular apps in their effort to identify the misbehaving ones. Telegram Desktop Application for Windows/Linux/Mac OS was among the apps they checked out. Bitcoin/Dogecoin wallets, Mumble, LibreOffice, OpenOffice and WinSCP all had security issues regarding the use of external URLs.”]
