 "title": "Post Carousel <= 4.0.8 - Unauthenticated Non-Public Post Type Information Exposure via Smart Search REST Endpoint",
 "description": "The Smart Post plugin for WordPress is vulnerable to Sensitive Information Exposure via the sps-blocks/v2/smart-search REST endpoint and the sp_smart_post_block_post_query AJAX action in all versions from 4.0.0 up to, and including, 4.0.8. This is due to these post queries using a request-supplied post type without restricting it to public post types. This makes it possible for unauthenticated attackers to retrieve titles, excerpts, authors and other details of published entries of non-public post types, such as WooCommerce coupons or other plugins' internal records.",
