Poor thinking, security-wise.  This still has a problem - if a remote attacker
can find a way to bypass the authentication and cause an SQL injection, they
can gain control, even if they can't find a way to bypass the authentication
and seize control of the SQLManager tool you provided.

If you need help in understanding why this is a problem, walk into your
boss's office and ask:

"OK, since I know you have tools to create and manage requests for stuff,
there's no problem if I create some requests myself, and trick you into signing
them to authorize doubling my salary and buying me a Porsche, right?"

After all, since he was provided a tool to manage purchase orders, it's
not a vulnerability if a fake one gets created, right? :)
