Using exec is a good use-case when you are on an SSH-connection, and want to "hand" an existing connection to another user without the need to reconnect. I wonder if there are vulnerabilities in terms of security with regard to this.

It's a direct process fork; nothing should be inherited by the new process... except environment variables and path! Oh, and potentially also ssh-agent. Envars and ssh-agent keyring could be worrisome!
