Critical Vulnerability in NestJS Devtools: Localhost RCE via Sandbox Escape
A flawed sandbox in @nestjs/devtools-integration lets attackers run code on your machine via CSRF, leading to full Remote Code Execution (RCE).

Advanced tools
Test your http clients with jest:
import { MockServer } from 'jest-mock-server';
import fetch from 'node-fetch';
describe('Testing node-fetch HTTP client', () => {
const server = new MockServer();
beforeAll(() => server.start());
afterAll(() => server.stop());
beforeEach(() => server.reset());
it('Receives a status over the network', async () => {
const route = server
.get('/')
// Look ma, plain Jest API!
.mockImplementationOnce((ctx) => {
// ...and plain Koa API
ctx.status = 200;
})
.mockImplementationOnce((ctx) => {
ctx.status = 201;
});
// Since we did not passed any port into server constructor, server was started at random free port
const url = server.getURL();
const res1 = await fetch(url);
expect(res1.status).toBe(200);
const res2 = await fetch(url);
expect(res2.status).toBe(201);
const res3 = await fetch(url);
expect(res3.status).toBe(404);
expect(route).toHaveBeenCalledTimes(3); // Yep, jest API again
});
});
