chore(deps): bump undici and wrangler in /worker

[dependabot]

Bumps undici to 7.28.0 and updates ancestor dependency wrangler. These dependencies need to be updated together.

Updates undici from 7.24.8 to 7.28.0

Release notes

Sourced from undici's releases.

v7.28.0

⚠️ Security Release

This release line addresses 7 security advisories, all shipped in v7.28.0.

Action required: Upgrade to undici 7.28.0 or later.

npm install undici@^7.28.0

The v7 line is not affected by GHSA-38rv-x7px-6hhq (CVE-2026-9675), which is an 8.x-only regression.

Note on GHSA-hm92-r4w5-c3mj: this fix shipped in v7.28.0, not the earlier 7.2x line — the vulnerable single-pool code was still present through v7.27.2. The per-origin pool fix is 3805b8f8 (#5041).

High severity

WebSocket DoS via fragment count bypass — CVE-2026-12151

GHSA-vxpw-j846-p89q · CWE-400, CWE-770 Fix: 8cb10f98 websocket: limit the number of fragments in a message (part of backport a027a4a0 Backport WebSocket maxPayloadSize fixes to v7.x, #5423)

A malicious WebSocket server can stream a large number of small or empty continuation frames. Undici enforced a limit on cumulative payload size but did not limit the number of fragments per message, leading to unbounded memory growth and denial of service.

• Affected: applications using new WebSocket(...) or WebSocketStream against untrusted endpoints.
• Workaround: none — upgrade is required.

Minor Changes

• #14474 aa5d580 Thanks @​WillTaylorDev! - Add cache options for WorkerEntrypoint exports

  You can now set cache options on WorkerEntrypoint exports and configure cross-version cache behavior globally:

  // wrangler.json
  {
    "cache": { "enabled": true, "cross_version_cache": true },
    "exports": {
      "default": {
        "type": "worker",
        "cache": { "enabled": false }
      },
      "Admin": {
        "type": "worker",
        "cache": { "enabled": true }
      }
    }
  }

  Wrangler sends the exports config to the deploy and version upload APIs alongside the global cache.enabled and cache.cross_version_cache settings. The platform resolves those global settings plus cache overrides on exports and validates which entrypoint names are cacheable.

• #14382 fd92d56 Thanks @​petebacondarwin! - Add support for declarative Durable Object exports

  wrangler deploy now accepts an exports map in wrangler.json as a declarative alternative to the legacy migrations array.

  Each entry in exports is keyed by Durable Object class name. type carries the export kind (currently always "durable-object"); the state field carries the lifecycle and defaults to "created" (live) when omitted:

  {
    "exports": {
      // Provision a new Durable Object class (`MyDO`)
      "MyDO": { "type": "durable-object", "storage": "sqlite" },
      // Delete Durable Object class (`OldGone`)
      "OldGone": { "type": "durable-object", "state": "deleted" },
      // Rename a Durable Object class (from `OldName` to `NewName`)
      "OldName": {
        "type": "durable-object",
        "state": "renamed",
        "renamed_to": "NewName"
      },
      "NewName": { "type": "durable-object", "storage": "sqlite" },
      // Transfer a Durable Object (`Outgoing`) to a new Worker (`target-worker`)
      "Outgoing": {
        "type": "durable-object",
        "state": "transferred",
