## Description

The Content Egg plugin for WordPress is vulnerable to Sensitive Information Exposure via the 'post_id' parameter of the render-blocks REST endpoint, the product data REST endpoint, and its shortcodes and blocks in all versions up to, and including, 12.0.0, due to the plugin rendering or returning the products attached to the requested post without checking that the post is public. The render-blocks endpoint accepts requests from anyone, and the product data endpoint served password-protected posts. This makes it possible for unauthenticated attackers to read the product data stored on draft, private or password-protected posts.
