Vulnerability location: /wp-content/plugins/website-faq/website-faq-widget.php
==============================================================================

     Lines 106-115:

          function displayAnswer()
          {
 	     global $wpdb;
             $master_table = $wpdb->prefix . "faq";
	     $category = $_POST['category'];
	     $searchtxt = $_POST['searchtxt'];
	     if($category!=0)
	     {
	        $sql = "SELECT * FROM $master_table WHERE faq_category=".$category." AND  faq_question LIKE '%".$searchtxt."%'";
	     }

Vulnerability Details: faq_category vulnerable to SQL injection
===============================================================

When submitting a query via the widget, intercept the post request via burp or other proxy to find the following:

              action=displayAnswer&category=1&searchtxt=[your query]

Changing category=1 to category=1 or 1=1 -- exposes the vulnerability, as it returns all FAQ results regardless of searchtxt value.
