  1. Description:
  This plugin allows users to thank/like other users threads/posts. In user profiles it shows your most liked post/thread, the post/thread subjects aren't sanitized to user input.
   
  
  2. Proof of Concept:
  
  - Use the following as the post/thread subject<script>alert('XSS')</script>
  - Get that post/thread liked by another user (or you)
  - Visit your profile to see alert.
  
  
  3. Solution:
  Update to v3.1.0
