CWE: CWE-352 \u2014 Cross-Site Request Forgery (CSRF)
The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request.

Code:
        reader.onload = function (e) {
            $(that).css("color", "green");
            $(that).closest(".imageContainer").find('.image_preview').css("display", "block");
            $(that).closest(".imageContainer").find('.previewing').attr('src', e.target.result);
            //$(that).closest(".imageContainer").find('.previewing').attr('width', 'auto');
            //$(that).closest(".imageContainer").find('.previewing').attr('height', '100%');
        };
