CVE-2025-11533 is an unauthenticated privilege escalation vulnerability in the WP Freeio plugin for WordPress affecting all versions up to and including 1.2.21. The flaw is in the plugin's process_register() function, which does not properly restrict or validate the WordPress role a newly registering user may request. As a result, an attacker can submit a registration request containing a privileged role value such as 'administrator', and the plugin will create the account with that role. Because the vulnerable registration workflow is exposed through the site's registration functionality, exploitation can be performed remotely via the public registration form or crafted HTTP POST requests without prior authentication.
