Input validation vulnerability in Botnet Attack Blocker 2.0.0

The Botnet Attack Blocker plugin for WordPress has a security issue that could allow hackers to inject harmful code into web pages. This can happen in versions up to and including 2.0.0 because the plugin does not properly clean up user input. As a result, attackers with subscriber-level access or higher can potentially execute their own code when someone visits a page that has been compromised.
