## Description

The review-schema plugin for WordPress is vulnerable to Sensitive Information Exposure via its generated JSON-LD structured data in all versions up to, and including, 3.1.3. This is due to the schema builders using the excerpt, saved AI schema text or post content of password-protected posts for the description, and emitting the full post content as articleBody, without checking whether the post is password-protected. This makes it possible for unauthenticated attackers to read the content of password-protected posts from the page source without knowing the password.
