Advisory
Source description from Wordfence Intelligence.
The All In One WP Security & Firewall plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 5.1.0. This is due to missing or incorrect nonce validation on the process_bulk_action function. This makes it possible for unauthenticated attackers to modify the plugin's block list table, via forged request granted they can trick a site administrator into performing an action such as clicking on a link.
