Input validation vulnerability in Spam protection, Anti-Spam, FireWall by CleanTalk 6.20

The Spam protection, AntiSpam, FireWall by CleanTalk plugin for WordPress has a security issue in versions up to 6.20. The problem is related to the apbct_admin__admin_bar__prepare_counters() function, which does not have proper validation of requests. This means unauthorised people can make requests that the administrator of the website will carry out without realising, such as clicking a link.
