Input validation vulnerability in Schema Scalpel 1.6.1

The plugin called Schema Scalpel for WordPress has a security issue called Stored Cross-Site Scripting. This happens when the plugin does not properly clean or protect user-supplied information before using it to create a type of code called JSON-LD schema markup. This could allow someone who is logged in with Contributor or higher access to put harmful code into a page that will run whenever someone else visits that page.
