Bump ws and wrangler

[dependabot]

Bumps ws to 8.21.0 and updates ancestor dependency wrangler. These dependencies need to be updated together.

Updates ws from 8.19.0 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';
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.

8.20.1

Updates wrangler from 4.59.3 to 4.95.0

Release notes

Sourced from wrangler's releases.

wrangler@4.94.0

Minor Changes

• #13897 52e9082 Thanks @​dario-piotrowicz! - Add automatic Cloudflare skills installation for AI coding agents

  Wrangler now detects AI coding agents and offers to install Cloudflare skill files from the cloudflare/skills GitHub repository. Users are prompted once interactively; subsequent runs skip the prompt. Use --install-skills to install without prompting.

• #13989 f598eac Thanks @​MattieTK! - Print a QR code alongside the tunnel URL when sharing via Cloudflare Tunnel

  When a tunnel is started (via wrangler dev --tunnel or the Vite plugin with tunnel: true), a scannable QR code is now printed to the terminal beneath the tunnel URL. This makes it easy to open the tunnel on a mobile device without manually copying the URL.

  The QR code uses Unicode block characters for a compact representation and is generated best-effort -- if generation fails for any reason, the tunnel URL is still displayed as before.

• #13467 3a1fbed Thanks @​deloreyj! - Add schedule property to Workflow bindings for cron-based triggering

  Note: This is a configuration-only change. Scheduled triggering of Workflow instances is not yet available — adding schedule to a Workflow binding will not result in scheduled invocations at this time. This change lays the groundwork for an upcoming feature.

  Workflow bindings in wrangler.json now accept an optional schedule field that configures one or more cron expressions to automatically trigger new workflow instances on a schedule.

  // wrangler.json
  {
    "workflows": [
      {
        "binding": "MY_WORKFLOW",
        "name": "my-workflow",
        "class_name": "MyWorkflow",
        "schedule": "0 9 * * 1"
      }
    ]
  }

  Multiple schedules can be provided as an array:

  {
    "workflows": [
      {
        "binding": "MY_WORKFLOW",
        "name": "my-workflow",
        "class_name": "MyWorkflow",
        "schedule": ["0 9 * * 1", "0 17 * * 5"]
      }
    ]
  }

  The schedule is sent to the Workflows control plane on wrangler deploy. Configuring schedule on a workflow binding that references an external script_name is an error — the schedule must be configured on the worker that defines the workflow.
