Fix Insecure API Management in Hapi

Insecure API management in Hapi usually manifests as exposed endpoints lacking rate limiting, proper authentication strategies, or granular authorization scopes. This 'open-door' policy invites automated scraping, credential stuffing, and Broken Object Level Authorization (BOLA) attacks. To secure a Hapi API, we must enforce a default authentication policy, integrate rate limiting, and use route-level scopes to validate resource ownership.

The Vulnerable Pattern

const Hapi = require('@hapi/hapi');

const init = async () => { const server = Hapi.server({ port: 3000 });

server.route({ method: ‘GET’, path: ‘/api/data/{userId}’, handler: (request, h) => { // VULNERABILITY: No authentication, no rate limiting, no authorization check. // Any attacker can iterate userId to scrape the entire database. return getDataForUser(request.params.userId); } });

await server.start(); };

The Secure Implementation

The secure implementation fixes three critical flaws. First, it registers 'hapi-rate-limit' to prevent DoS and brute-force attempts. Second, it implements 'hapi-auth-jwt2' and sets it as the default strategy, ensuring no endpoint is public by accident. Third, it uses Hapi's dynamic scoping ('user-{params.userId}') to ensure that authenticated users can only access their own data, effectively mitigating BOLA vulnerabilities. By moving logic from the handler to the route configuration, we reduce the risk of developer error in access control checks.

const Hapi = require('@hapi/hapi');
const Jwt = require('hapi-auth-jwt2');
const RateLimit = require('hapi-rate-limit');

const init = async () => { const server = Hapi.server({ port: 3000 });

// Register security plugins await server.register([ Jwt, { plugin: RateLimit, options: { userLimit: 50, pathLimit: 10 } } ]);

server.auth.strategy(‘jwt’, ‘jwt’, { key: process.env.JWT_SECRET, validate: async (decoded) => ({ isValid: !!decoded.id, credentials: decoded }) });

server.auth.default(‘jwt’);

server.route({ method: ‘GET’, path: ‘/api/data/{userId}’, options: { auth: { // Enforce scope: User must have admin role OR match the userId being requested access: { scope: [‘admin’, ‘user-{params.userId}’] } }, handler: (request, h) => getDataForUser(request.params.userId) } });

await server.start(); };
