Input validation vulnerability in Category and Taxonomy Meta Fields 1.0.0

A plugin called “Category and Taxonomy Meta Fields” for WordPress has a security issue where a type of hacking called “Stored Cross-Site Scripting” can happen. This is because the plugin does not properly check and protect certain information that is entered by users. This means that hackers who have high-level access to the website can add their own code to pages, and it will run when someone views those pages. This only affects websites with multiple pages and websites where a certain security setting is not turned on.
