WP/Plugin Version in HTML source

Hi, on any browser when you “view source”, this plugin reveals the following:

var wpversion = "4.6.1";
var agca_version = "5.6.4";

This is a potential threat. This should not be revealed. Can you work on this or is there any existing work around?

The full code for REF below: (all inline JS scripts on the page)

<script type="text/javascript">
                var wpversion = "4.6.1";
                var agca_version = "5.6.4";
                var agca_debug = false;
                var jQueryScriptOutputted = false;
                var agca_context = "page";
                var agca_orig_admin_menu = [];
                function initJQuery() {
                    //if the jQuery object isn't available
                    if (typeof(jQuery) == 'undefined') {
                        if (! jQueryScriptOutputted) {
                            //only output the script once..
                            jQueryScriptOutputted = true;
                            //output the script (load it from google api)
                            document.write("<scr" + "ipt type=\"text/javascript\" src=\"//ajax.googleapis.com/ajax/libs/jquery/3.0.0/jquery.min.js\"></scr" + "ipt>");
                        }
                        setTimeout("initJQuery()", 50);
                    } else {
                        jQuery(function() {
                            try
                            {
                                                                jQuery('#wpadminbar').show();
                                
                                        
                                                                        

                    jQuery("#wphead #header-logo").css("display","none");
            jQuery("ul#wp-admin-bar-root-default li#wp-admin-bar-wp-logo").css("display","none");

                                                                                            var alltext="";
            alltext="";
            jQuery('li#wp-admin-bar-my-account').css('cursor','default');
            alltext = jQuery('li#wp-admin-bar-my-account').html();
            if(alltext!=null){
            var parts = alltext.split(',');
            alltext = "As-Salaam-Alaikum" + ", " + parts[1];
            }
            jQuery("li#wp-admin-bar-my-account").html("<a href=\"#\" class=\"ab-item\">"+alltext+"</a>");

                                        
                                    }catch(ex){}
                        });
                    }
                }
                initJQuery();
            </script>
