Advisory

Source description from Wordfence Intelligence, credited to Ángel Santana.

The OMGF plugin for WordPress is vulnerable to Denial of Service in all versions up to, and including, 6.3.10. This is due to missing capability check and nonce verification on the admin_init handler that triggers a slow server-side loopback request. This makes it possible for unauthenticated attackers to exhaust the site's PHP worker pool by triggering slow server-side loopback requests without authentication, making the site unavailable.
