Common Vercel Vulnerabilities We Detect

AI Agents Built for Vercel

Our agents are trained on Vercel architecture and equipped with specialized tooling for serverless functions, edge functions, and Next.js security testing. They understand the nuances of Vercel security that most pentesters miss.

Environment Variable Exposure

high

Sensitive environment variables exposed to the client bundle or accessible through API routes. Attackers can extract API keys, database credentials, and secrets.

// Vulnerable: Exposed to client const apiKey = process.env.API_KEY export default function Page() { // API_KEY is bundled in client JS! return <div>{apiKey}</div> }
// Fixed: Use NEXT_PUBLIC_ prefix intentionally // Keep secrets server-side only export async function getServerSideProps() { const data = await fetch(url, { headers: { Authorization: process.env.API_KEY } }) return { props: { data } } }

Serverless Function Injection

high

API routes and serverless functions vulnerable to injection attacks through unvalidated user input. Can lead to data breaches or remote code execution.

// Vulnerable: Direct query construction export async function GET(req: Request) { const { searchParams } = new URL(req.url) const id = searchParams.get("id") // SQL injection possible! const user = await db.query(`SELECT * FROM users WHERE id = ${id}`)
// Fixed: Parameterized queries export async function GET(req: Request) { const { searchParams } = new URL(req.url) const id = searchParams.get("id") // Safe parameterized query const user = await db.query( "SELECT * FROM users WHERE id = $1", [id] )

Missing Authentication on API Routes

high

API routes accessible without proper authentication checks. Attackers can access sensitive endpoints and perform unauthorized actions.

// Vulnerable: No auth check export async function POST(req: Request) { const { userId, role } = await req.json() // Anyone can change roles! await db.updateUser(userId, { role }) return Response.json({ success: true }) }
// Fixed: Verify authentication import { auth } from "@/lib/auth" export async function POST(req: Request) { const session = await auth() if (!session?.user?.isAdmin) { return Response.json({ error: "Unauthorized" }, { status: 401 }) } // Proceed with admin action }

Edge Function Misconfigurations

medium

Edge functions with overly permissive CORS, missing rate limiting, or improper header handling can be exploited for data theft or service abuse.

// Vulnerable: Wildcard CORS export const config = { runtime: "edge" } export default function handler(req: Request) { return new Response(sensitiveData, { headers: { "Access-Control-Allow-Origin": "*" // Dangerous! } }) }
// Fixed: Restrict CORS to trusted origins const ALLOWED_ORIGINS = ["https://myapp.com"] export default function handler(req: Request) { const origin = req.headers.get("origin") const corsOrigin = ALLOWED_ORIGINS.includes(origin) ? origin : "" return new Response(data, { headers: { "Access-Control-Allow-Origin": corsOrigin } }) }
