  - CVE-2022-4471: The plugin does not validate and escape some of its shortcode attributes before
  outputting them back in a page/post where the shortcode is embed, which could allow users with the
  contributor role and above to perform Stored Cross-Site Scripting attacks.

  Note: CVE-2022-4471 got only partly fixed in 5.30.2 and a final fix for a second attack path was
  included in version 5.30.3.

  - CVE-2022-45374: The plugin does not validate a parameter before using it in an include
  statement, allowing any authenticated users, such as subscriber to perform LFI attacks.");
