Bump undici and wrangler in /web

[dependabot]

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

Updates undici from 7.24.4 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).

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

GHSA-vxpw-j846-p89q · CWE-400, CWE-770 Fix:8cb10f98websocket: limit the number of fragments in a message (part of backport a027a4a0Backport 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.

Updates wrangler from 4.82.2 to 4.110.0

Release notes

Sourced from wrangler's releases.

wrangler@4.110.0

Minor Changes

• #145910283a1f Thanks @​dario-piotrowicz! - Send npm package dependency metadata with worker uploads

  Wrangler now collects npm package dependency information from the project's package.json at deploy and version upload time, and includes it in the upload metadata sent to the Cloudflare API. This enables dependency analytics and future features like vulnerability alerting.

  The collected data includes the package name, the version constraint from package.json, and the exact installed version from node_modules. Both dependencies and devDependencies are included, while workspace packages, local packages, and unresolvable packages are excluded. The list is capped at 200 entries per upload.

  To opt out, set dependencies_instrumentation.enabled to false in your Wrangler configuration file:

  {
  "dependencies_instrumentation": {
  "enabled": false
  }
  }

• #145351b965c5 Thanks @​Naapperas! - Support dynamic retry delays for Workflow steps in local dev

  A step's retries.delay can now be a function that computes the delay per failed attempt, in addition to a static duration. The function receives { ctx, error } and returns a delay (a number of milliseconds or a duration string like "30 seconds"), and its result is fed into the configured backoff.

  awaitstep.do("call flaky API",{retries: {limit: 5,backoff: "constant",delay: ({ ctx })=>ctx.attempt*1000,},},async()=>{/* ... */});

  The function is invoked once per failed attempt with a 5 second timeout. If it throws, times out, or returns an invalid value, the step fails without further retries.

Patch Changes

• #145897b28392 Thanks @​jamesopstad! - Fix runtime type caching when wrangler dev auto-regenerates types

  When dev.generate_types (or wrangler dev --types) regenerated an out-of-date worker-configuration.d.ts, the written file omitted the // Begin runtime types marker (and the /* eslint-disable */ header) that wrangler types writes. As a result, later runs could not detect the cached runtime types and always regenerated them. The auto-regenerated file now matches wrangler types output, restoring the cache.
