About Laravel 5.1 Security

I'm newbie on developing projects in Laravel 5.1

I want to learn the how can I avoid security risks. What kind of attacks are secured by Laravel? And what kind of attacks Laravel is not secure?

Using middleware is good way to handling authorizations.

And I know Laravel is secured for CSRF attacks.

Is there any thing that should i know ? What about SQL Injection. Is Laravel secure or not?
