Fix registration and login pages
Fix the registration and login page there isn't a CAPTHCA or even a CAPTCHA on the page to respond to but access is denied anyway.

This is kind of embarrassing TBH. CVE is the #1 DB for security vulns an their registration captcha is busted? I'm going to assume the admins don't care because the OP posted this on 8/14/17 and it's now 10/3/17....still busted.
Actually the captcha is shown via insecure HTTP but this is obviously not recommended.
Please, provide a secure possibility to sign up, especially as your role as a security (!) database.
