Input validation vulnerability in WP Compare Tables 1.0.5

The WP Compare Tables plugin for WordPress has a security issue that allows hackers to manipulate settings and insert harmful scripts. This problem affects all versions of the plugin, including 1.0.5. The vulnerability is caused by a lack of proper verification, which means that attackers without valid credentials can exploit it. They can do this by tricking a website administrator into taking a certain action, like clicking on a link.
