Description The plugin does not validate and escape some of its Pricing Table options before outputting them back in a page/post where the related shortcode is embed, which could allow users with the author role and above to perform Stored Cross-Site Scripting attacks

- Create a new Pricing Table
- Fill it with valid information, except for the "CSS classes", "Add custom code here" and "Button URL " sections
- Payloads:
  - CSS classes: " onmouseover='alert(/CSS/);'
  - Custom Code: <script>alert(/CustomCode/);</script>
  - Button URL: javascript:alert(/XSS/) (requires the Custom Code to be empty, and the '_rpt_open_newwindow' post meta to be anything other than 'newwindow')
