Description
The Ajax Search Lite plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 4.14.5, due to the unauthenticated ajaxsearchlite_search action accepting any post type sent in the 'customset' option instead of limiting it to the configured post types. This makes it possible for unauthenticated attackers to search non-public post types the administrator did not expose, such as WooCommerce coupons, stored form messages or templates, and read their titles and content, for posts in a searched status (published by default).
