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:
            success: function(productUnit, status) {
                if (status == "success") {

                    /* Change the product Price */
                    $(selector).closest("tr").find(".productPurchasePrice").val(productUnit.pp);
                    $(selector).closest("tr").find(".productMainPurchasePrice").val(productUnit.pp);

                    /* Calculate all data */
                    self.calculateEachProduct(selector);
                    self.grandTotal();

                }
            }
