## Description

The SchemaEngine AI – AI Schema Markup, Reviews & Rich Snippets for SEO plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.1.5 via the 'id' attribute of the [rtrs-affiliate] shortcode due to missing validation of the post type, status and password protection of the referenced post. This makes it possible for authenticated attackers, with contributor-level access and above, to embed the shortcode with the ID of a draft, private, trashed or password-protected affiliate post and expose its review box data (title, summary, rating criteria, pros and cons, prices and button text and URL).
