## Description

The Schema & Structured Data for WP & AMP plugin for WordPress is vulnerable to Insecure Direct Object Reference via the 'post_id' parameter of the front-end review filter and pagination AJAX actions (saswp_rf_template_review_filter, saswp_rf_template_pagination) in all versions up to, and including, 1.69, due to missing validation that the requested post is publicly viewable by the current visitor. The only check is a nonce that is printed on public pages showing the review form, and an empty post_id queries comments across all posts. This makes it possible for unauthenticated attackers to retrieve the approved reviews and comments, and the review counts, of private, draft, pending or password-protected posts.
