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

The Ninja Forms - File Uploads plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.3.29. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to read all plugin debug log entries stored in the wp_nf3_log table or permanently delete all rows from that table.
