Codehub.go TestCase2 is unsolvable

It appears as if Codehub.go is unsolvable, the 2nd test case has no way of passing even with the security issues fixed.

Thanks Andrej. Will check it.

server tests looks okay. @andrej.kikelj can you please confirm you have your latest code pushed?

Without disclosing too much about the solution, from what I can see the security issue has not been addressed.

Feel free to DM me.
