  The WordPress plug-in 'UserPro' uses a Instagram library (Instagram PHP API V2 by cosenary) that
  is vulnerable for Reflected Cross-Site Scripting (XSS).
  
  There is more vulnerable code in 'UserPro' core, might release that later.
  
  As of today (25 August 2019) this issue is unfixed.
  
  Vulnerable code: (success.php on line 36)
  
  if (isset($_GET['error'])) {
  echo 'An error occurred: ' . $_GET['error_description'];
  }
