Description
The VK Filter Search plugin for WordPress is vulnerable to Sensitive Information Exposure via the 'post_type' and 'vkfs_post_type' parameters in all versions up to, and including, 2.20.7. This is due to the plugin passing user-supplied post types directly into the search query without restricting them to public or publicly queryable post types. This makes it possible for unauthenticated attackers to query and view content from non-public post types through the site search.
