The vulnerability has since been patched.
Flaw in DNS
Saccomanni said that he noticed the flaw in GoDaddys DNS management actions.
GoDaddy however had no security in place so Saccomanni could easily exploit the vulnerability.
Eventually I reached someone through Twitter from @GoDaddyHelp.
I was told there was no timeline for a fix.
However now the vulnerability has been patched.
