Bump undici and wrangler

[dependabot]

Bumps undici to 7.29.0 and updates ancestor dependency wrangler. These dependencies need to be updated together.

Updates undici from 7.24.8 to 7.29.0

Release notes

Sourced from undici's releases.

v7.29.0

⚠️ Security fixes

High severity

• GHSA-4cwx-7wf7-3272: malformed qualified private Cache-Control directives could cause cross-user information disclosure in shared caches or a parse-time crash. The cache parser now treats empty qualified directives conservatively and safely handles mixed qualified and unqualified directives. Fixed by 9f10f1e9, with regression coverage in 466e99d1.

Medium severity

• GHSA-m8rv-5g2x-5cg5: a malicious type property on a duck-typed blob-like HTTP/1.1 request body could inject CRLF sequences into the generated content-type header. Undici now coerces and validates the value before adding it to the request. Fixed by 33928bc2.
• GHSA-jr45-8vmc-qm54: optional whitespace around = in qualified no-cache and private directives could bypass shared-cache restrictions and disclose authenticated data across users. Cache-Control parsing now normalizes these forms and applies conservative cache decisions. Fixed by 98011a86.
• GHSA-8xcm-r25x-g524: the retry interceptor could expose a stale Content-Length after resuming a partial response, potentially causing downstream response desynchronization, hangs, or corruption. Undici now rejects partial responses whose Content-Length is inconsistent with Content-Range. Fixed by 1b5a5312, with corrected fixtures in 4a9dafb1.
• GHSA-v3r7-h72x-cjcm: unsanitized domain and unparsed values passed to setCookie() could inject cookie attributes. Undici now validates cookie domains, paths, and unparsed attributes more strictly. Fixed by 3bf91ddb.

Full Changelog: nodejs/undici@v7.28.0...v7.29.0

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).

Updates wrangler from 4.93.0 to 4.125.0

Release notes

Sourced from wrangler's releases.

wrangler@4.125.0

Minor Changes

• #14995 59872c4 Thanks @​ThomasRubini! - Add connect trigger for raw sockets

  You can now configure a Worker to receive raw socket connections during wrangler dev, delivered directly to the Worker's connect(socket, env, ctx) handler:

  {
    "connect": [{ "protocol": "tcp", "port": 5432 }]
  }

  Each entry opens a listening socket on 127.0.0.1 (or the given address) that forwards incoming connections straight to the Worker, bypassing the local dev HTTP entry point. This requires the experimental compatibility flag. Only "tcp" is supported at the moment.

  @cloudflare/config also supports declaring this trigger via triggers.connect(...), which lowers to the connect field above:

  import { defineWorker, triggers } from "@cloudflare/config";
  export default defineWorker({
  triggers: [
  triggers.connect({ protocol: "tcp", port: 5432, address: "127.0.0.1" }),
  ],
  });

• #15172 c68f9cb Thanks @​WillTaylorDev! - Add container support to worker previews

  Worker previews now support containers through a new previews.containers configuration block. Container configuration doesn't inherit, so declare containers explicitly in the previews block to enable them for previews. This mirrors how previews.durable_objects works today. Wrangler names each preview container application {worker_name}_{preview_slug}_{class_name}, normalising and shortening the result to what the API accepts. Either change appends a short digest of the composed name, so two names that would otherwise land on one stay distinct. An entry cannot set its own name, because application names are unique to an account and a fixed name would collide between two previews of the same Worker. A Durable Object class is backed by at most one container application, so the validator rejects two entries that share a class_name. Wrangler skips container applications bound to Durable Object classes that another Worker implements through script_name, because the implementing Worker owns its own container application. A binding is not required: a Durable Object declared through migrations or exports and reached only over ctx.exports can still back a container. Every entry must set class_name. A previews.containers entry whose class_name matches no Durable Object class at all is rejected before the preview deployment is created, so a typo fails loudly instead of producing a preview with no container.

  Wrangler creates the container applications on wrangler preview. Deleting a preview tears them down server side, so wrangler preview delete doesn't remove them.

  Container build and deploy progress prints to stdout. wrangler preview --json suppresses wrangler's own output so it doesn't interleave with the payload, and warnings and errors still go to stderr. Docker's build output and the progress spinner write to stdout directly and bypass that suppression, so parse --json from a non interactive shell, where the spinner is skipped, and prefer a prebuilt image over a Dockerfile.

• #15174 649f667 Thanks @​WillTaylorDev! - [private beta]: Create the parent Worker automatically when wrangler preview targets one that doesn't exist yet

  Previews hang off a parent Worker, so running wrangler preview before the Worker had ever been deployed failed with a raw API error naming the Preview endpoint. Wrangler now offers to create an empty parent Worker and then carries on creating the Preview. The parent uses the same workers.dev and Preview URL settings that wrangler deploy would resolve, without applying routes or cron triggers. In non-interactive environments, Wrangler creates the Worker without asking.

• #14735 30c2d47 Thanks @​vaishnav-mk! - Add individual and batch Workflow instance deletion to the runtime and SDK.

  • WorkflowInstance.delete() deletes one instance. Self-deletion stops the current execution.
  • env.MY_WORKFLOW.deleteBatch(instanceIds) deletes up to 100 instances and returns { deleted, errors } per input position.
  • wrangler workflows instances delete <name> [id..] deletes instances remotely or with --local; IDs can also come from a JSON array passed with --filename, with a combined limit of 100.
