Generate Security.txt <= 1.0.13 - Missing Authorization to Authenticated (Subscriber+) Security.txt Deletion via delete_securitytxt AJAX Action

The Generate Security.txt plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.0.13. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete the site's security.txt file from the server filesystem or create the .well-known directory by directly invoking the delete_securitytxt or create_wellknown_folder AJAX actions.
