How fix CRLF Injection Vue.JS
I have the vulnerability CRLF.
This my code:
const path = require("path");
require("dotenv").config({
path: path.resolve(process.cwd(), ".env.prod"),
});
const express = require("express");
const consola = require("consola");
const cors = require("cors");
const http = require("http");
const helmet = require("helmet");
// Import and Set Nuxt.js options
const { Nuxt, Builder } = require("nuxt");
const app = express()
const httpServer = http.createServer(app);
const config = require("../../nuxt.config.js");
The report Veracode show with vulnerability the line: const app = express()
How can fix the vulnerability?

Hi @FDomenike019050 (Community Member) ,
Veracode Static Analysis detects CRLF flaws by looking at places where injecting a CR and/or LF character might be interpreted as a control character. For example in console.log statements or when modifying raw HTTP Response headers.
Initializing express with 'const app = express()' is unlikely to be reported for a CRLF flaw. There may be a mismatch in the source code scanned with Veracode Static Analysis and reviewed in the Platform or IDE.
I would recommend doing a new fresh scan and ensuring you are reviewing the line of code reported by Veracode Static Analysis.
If this does not resolve the issue I would recommend you contact our technical support team. Here's how you can log a case:
1. Navigate to the upper right corner of any page in the Community, click on your user avatar.
2. Select Contact Support from the drop-down menu.
Thank you,

Hi @FDomenike019050 (Community Member),
Is there a chance the flaw could be CSRF (CWE-532) rather than CRLF? If it is the case that that the flaw reported was CSRF and not CRLF, you may wish to consider making use of the csurf express middleware (https://github.com/expressjs/csurf) to defend against CSRF attacks. Alternatively you may elect to propose a mitigation if there are other controls in place to defend against CSRF attacks.
Thanks,
