Input validation vulnerability in Cost Calculator Builder 3.2.74

The Cost Calculator Builder plugin for WordPress has a security issue called Stored Cross-Site Scripting in versions up to 3.2.74. This happens because the plugin does not properly clean up the input and output of information. This means that someone with high access to the website can add harmful code to a page that will run when someone views it. This problem only affects websites with multiple sites or websites that have disabled a security feature called unfiltered_html.
