SearchWP Live Ajax Search <= 1.6.1 is vulnerable to Unauthenticated Arbitrary Post Title Disclosure vulnerability

The SearchWP Live Ajax Search plugin for WordPress is vulnerable to arbitrary post title disclosure in versions up to, and including, 1.6.1. This is due to insufficient checking of a post status before displaying to a user. This makes it possible for unauthenticated attackers to view post titles even when they are not in a 'publish' state.
