Advisory

Source description from Wordfence Intelligence, credited to Evex.

The Ajax Search Lite plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the wpdreams_ajaxinputcallback function in versions up to, and including, 3.10. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to bypass restricted actions, which can lead to remote code execution.
