Input validation vulnerability in Content Views – Post Grid & Filter, Recent Posts, Category Posts, & More (Gutenberg Blocks and Shortcode) 3.7.1

A popular WordPress plugin called “Content Views – Post Grid & Filter, Recent Posts, Category Posts, & More” has a security issue that can put websites at risk. This is because the plugin does not properly clean up the information it receives and sends out, which makes it vulnerable to a type of attack called “Stored Cross-Site Scripting.” This means that hackers with certain levels of access can insert harmful code into pages, which will be executed when someone visits that page.
