CVE-2021-25101: Anti-Malware Security and Brute-Force Firewall < 4.20.94 - Admin+ Reflected Cross-Site Scripting

The Anti-Malware Security and Brute-Force Firewall WordPress plugin before 4.20.94 does not sanitise and escape the POST data before outputting it back in attributes of an admin page, leading to a Reflected Cross-Site scripting. Due to the presence of specific parameter value, available to admin users, this can only be exploited by an admin against another admin user.
