## Description

The Better Search plugin for WordPress is vulnerable to Sensitive Information Exposure via the 'post_type' search parameter in all versions up to, and including, 4.5.2 due to the parameter being passed into the search query without restricting it to searchable post types, combined with a default post status that included 'inherit'. This makes it possible for unauthenticated attackers to search for and view revision content of draft, private and password-protected posts, as well as internal content such as menu items, through front-end search results.
