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
JSONPlaceholder is a simple fake REST API for testing and prototyping.
It's like an image placeholder but for web developers.
JSONPlaceholder is powered by JSON Server.
Most of the time when trying a new library, hacking a prototype or following a tutorial, I found myself in need of some data.
I didn't like the idea of using some public API because I had the feeling that I was spending more time registering a client and understanding a complex API than focusing on my task.
But I liked the idea of image placeholders for web designers. So I decided to code a little Express server inspired by that and here is JSONPlaceholder.
You can find it running here and are free to use it in your developments: http://jsonplaceholder.typicode.com.
Or you can run it locally:
$ npm install -g jsonplaceholder
$ jsonplaceholder
I hope you will find it useful.
Let's start with resources, JSONPlaceholder provides the usual suspects:
Here's some code using jQuery showing what can be done with JSONPlaceholder. Since GitHub loads jQuery, you can simply copy and paste these examples in a console.
$.ajax('http://jsonplaceholder.typicode.com/posts/1', {
method: 'GET'
}).then(function(data) {
console.log(data);
});
$.ajax('http://jsonplaceholder.typicode.com/posts', {
method: 'GET'
}).then(function(data) {
console.log(data);
});
// POST adds a random id to the object sent
$.ajax('http://jsonplaceholder.typicode.com/posts', {
method: 'POST',
data: {
title: 'foo',
body: 'bar',
userId: 1
}
}).then(function(data) {
console.log(data);
});
/* will return
{
id: 101,
title: 'foo',
body: 'bar',
userId: 1
}
*/
Note: the resource will not be really created on the server but it will be faked as if.
$.ajax('http://jsonplaceholder.typicode.com/posts/1', {
method: 'PUT',
data: {
id: 1,
title: 'foo',
body: 'bar',
userId: 1
}
}).then(function(data) {
console.log(data);
});
/* will return
{
id: 1
title: 'foo',
body: 'bar',
userId: 1
}
*/
$.ajax('http://jsonplaceholder.typicode.com/posts/1', {
method: 'PATCH',
data: {
title: 'foo'
}
}).then(function(data) {
console.log(data);
});
/* will return
{
id: 1
title: 'foo',
body: 'quia et suscipit [...]',
userId: 1
}
*/
Note: the resource will not be really updated on the server but it will be faked as if.
$.ajax('http://jsonplaceholder.typicode.com/posts/1', {
method: 'DELETE'
});
Note: the resource will not be really deleted on the server but it will be faked as if.
Basic filtering is supported through query parameters.
// Will return all the posts that belong to the first user
$.ajax('http://jsonplaceholder.typicode.com/posts?userId=1').then(function(data) {
console.log(data);
});
One level of nested route is available.
$.ajax('http://jsonplaceholder.typicode.com/posts/1/comments').then(function(data) {
console.log(data);
});
// Which is equivalent to /comments?postId=1
Here's the list of available nested routes:
$.ajax('http://jsonplaceholder.typicode.com/posts/1', {
dataType: 'jsonp'
}).then(function(data) {
console.log(data);
});
