+ addition. You can try uploading a readme.txt file in the root folder of ajax search pro on the server: wp-content/plugins/ajax-search-pro/
I attached the readme.txt file to this post. It may help the wpsec crawler to get the correct plugin version, and report the correct results.
If you cannot see the attachment, the file is also available here: https://gist.github.com/anag0/2a82a4288e6cc2dcb4b5ea3b24e97a09
