Deny DB Access for Exploits

[domenukk]

This PR denies DB access for the exploit method.
In general, this is fine, the only issue I see is that, right now, we don't expose any way to use attackinfo in exploits. Maybe users need the db to emulate attackinfo for now?

We actually do have the attack_info available in the exploit-Method and this is also set by enochecker_test. Although that might be missing from the web intreface atm
