Advisory
Source description from Wordfence Intelligence, credited to AndrewN.
The SchemaEngine AI – AI Schema Markup, Reviews & Rich Snippets for SEO plugin for WordPress is vulnerable to Reflected Cross-Site Scripting in all versions up to, and including, 3.1.4. This is due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
