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 8.18.0 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 4.91.0 to 4.108.0

Release notes

Sourced from wrangler's releases.

wrangler@4.108.0

Minor Changes

• #14312 54f74b8 Thanks @​MattieTK! - Delegate agent-driven static Pages deploys to Workers

  When wrangler pages deploy or wrangler pages project create is run by an AI coding agent against a brand-new, purely static project, Wrangler now delegates it to Workers static assets (using autoconfig) instead of Cloudflare Pages. Accounts that already have Cloudflare Pages projects, non-agent (human) sessions, and projects using Pages features that can't be carried across to Workers (Pages Functions, a _worker.js, or a _routes.json file) are unaffected and continue to use Pages. Passing --force to either command opts out of the delegation and deploys to Pages directly. Once the Workers deploy starts it is not silently swapped back to Pages: if it fails, the error is surfaced and the --force opt-out is suggested.

Patch Changes

• #14567 0852346 Thanks @​dependabot! - Update dependencies of "miniflare", "wrangler", "create-cloudflare"

  The following dependency versions have been updated:

  Dependency	From	To
  workerd	1.20260702.1	1.20260706.1
  @​cloudflare/workers-types	4.20260702.1	5.20260706.1

• #14312 54f74b8 Thanks @​MattieTK! - Avoid silently overwriting an existing Worker during non-interactive deploys that cannot prove they own the name

  A non-interactive deploy (an agent, CI, or the agent-delegated wrangler pages deploy) has no way to prompt before overwriting a Worker, so it now stops if the target name is already taken and this run cannot show it owns that Worker. This applies when there is no Wrangler configuration file naming the Worker and either the name was generated automatically or the deploy is the Pages-to-Workers delegation (where the name carried across is a Pages project name, not proof of Worker ownership). The check reuses the service metadata the deploy already fetches, so it adds no extra API calls.

  Deploys are unaffected when a configuration file names the Worker (so repeat deployments continue to update it), and interactive deploys keep their existing confirmation flow. To update an existing Worker in one of the guarded cases, add a Wrangler configuration file naming it, or deploy under a different name.

Patch Changes

• #14514 d88555e Thanks @​dependabot! - Update dependencies of "miniflare", "wrangler"

  The following dependency versions have been updated:

  Dependency	From	To
  workerd	1.20260701.1	1.20260702.1

• #14564 5fd8bee Thanks @​jibin7jose! - Fix an issue where wrangler dev would not override config vars with values from .dev.vars during local development when the secrets field was defined in the configuration file.

• #14332 5d9990e Thanks @​Divkix! - Fix misleading error guidance when deploying a new Worker with secrets.required

  When a Worker declares secrets.required and has never been deployed before, the previous error message suggested running wrangler secret put <NAME>, which doesn't work because the Worker doesn't exist yet.

  The one path that does work — wrangler deploy --secrets-file <path> — was not mentioned anywhere in the error output.

  The pre-deploy error now explains that wrangler secret put cannot be used for a new Worker, and directs users to the --secrets-file flag instead. The post-deploy error for existing Workers now also mentions --secrets-file alongside wrangler secret put.

• #14507 bf49a41 Thanks @​joey727! - Fix a potential crash when displaying certain CLI output
