- Permanently delete that thread

- Alert is located in threads trash bin localhost/[path]/admin/index.php?module=tools-trashbin and localhost/admin/index.php?module=tools-trashbin&action=posts

- Reply to a post and change the subject to the following<script>alert('XSS')</script>

- Permanently delete that post

- Alert is located in posts trash bin localhost/[path]/admin/index.php?module=tools-trashbin&action=posts
