No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

The Prevent Direct Access – Protect WordPress Files plugin for WordPress is vulnerable to unauthorized access of protected files due to insufficient token validation in the get_advance_file_by_url() method in all versions up to, and including, 2.8.8.8 The method uses a SQL LIKE operator for token lookup without escaping wildcard characters via $wpdb->esc_like(). This makes it possible for unauthenticated attackers to bypass the private token requirement by supplying SQL wildcard characters (such as %) as the token value, matching any record in the plugin's file table and downloading any protected file.
