Description

The Generate Security.txt plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.0.12. 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.
