Servers already crashed because of the action described above. If there's no security issue how someone was able to crash them just like that at the first place? I get it that you need to have privileges, you need to pay to get access to server files, and every action executed with privileges will leave a mark, so it all will be easily sorted out, but it doesn't remove the fact that crashing is still possible.
So as long as it's possible, I find it as an issue and if it's not a security issue then what is it?
If you give your computer's password to a friend and he comes in and formats your drive, it's not a security issue to do with your OS (be it Windows, Mac OS or Linux).
EDIT: Whoops, it's locked
