Is it possible to exploit Teamviewer shared clipboard to send malicious code to Guest?

Recently, while I was using TeamViewer, I noticed that the clipboard is shared between host and guest.

If user A allows user B to connect, when user A copies something user B has it on his clipboard, and the same thing happens if user B copies something.

I know that clipboard is not only text, but it can hold a lot of different types of data.

My question is: Can user B copy some content (that contains malicious code) that will be executed on user A PC when user A paste that content?

    Hello @Jereme13265,

    Technically, yes - if user A executes what user B gives to him, then the command will be effective on user A.

    You can disable the clipboard synchronization within the Advanced TeamViewer options:
