I don't think there's a CVE number available for the SquirrelMail "issue",
but I also highly doubt that it's actually a vulnerability.

What they basically assert is, that as an authenticated user using the
POP3 fetch mail plugin, you could repeatedly change the POP3 server
settings and as such could 'portscan' a remote target.

This seems just as much a vulnerability as that you could use telnet, or
fetchmail, or Thunderbird, to be a 'portscanner', as these all have the
option to change a remote server address at will. Or that having a shell
account at a system is a security vulnerability as you would be able to
write a bash script to repeatedly netcat to remote hosts. I don't buy

Note that you need to be an authenticated user to do this.
