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
