More information about how my script will be accepted

I submited my script and I received this review

Comments from your Quality team

  • Please make sure the code adheres to PSR standards.
  • Make sure that the code doesn’t raise any PHP errors, notices or warnings. Please set error_reporting(E_ALL)
  • Please double check for common security vulnerabilities: SQL injection, XSS, CSRF etc
  • Please make sure the item doesn’t contain any encrypted code or a third party licensing system.

Does it mean that I have all this problems in my script ?
If so, i thinked that Laravel securise himself the CSRF, XSS and SQL injection… Am I wrong ?
I don’t have any encrypted code or a third party licensing system so why do i have it in the comment ?
