It seems like RustDesk has an known vulnerability in e2ee.
If you translate it step-by-step with Deepl you will see they seem to talk about decrypting data that should be end to end encrypted using a server RustDesk using for communicating.
Maybe. But most users will just download the app and use it. Without setting up their own server. And in my opinion, a working e2ee should be default for such an important task. https://rustdesk.com/ :
Security
End-to-end encryption.
Maybe someone could check this problem and add “known vulnerability” to the description of the app?
