deps(web)(deps): bump undici and @cloudflare/vite-plugin in /web

[dependabot]

Bumps undici to 7.28.0 and updates ancestor dependency @cloudflare/vite-plugin. These dependencies need to be updated together.

Updates undici from 7.25.0 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.

Updates @cloudflare/vite-plugin from 1.37.3 to 1.42.1

Release notes

Sourced from @​cloudflare/vite-plugin's releases.

@​cloudflare/vite-plugin@​1.42.1

Patch Changes

• #14366 c6579d3 Thanks @​jamesopstad! - Resolve relative cf-worker entrypoint imports relative to the importing module

  When loading the experimental cloudflare.config.ts, a relative entrypoint imported with import ... with { type: "cf-worker" } (e.g. ./src/index.ts) is now anchored to the module where the import is written, rather than being passed through verbatim and later resolved against the top-level config file. This fixes incorrect resolution when the import lives in a file other than the entry config — for example a config that re-exports from a nested file.

  Bare specifiers (such as @scope/pkg) and virtual modules (such as virtual:foo) are still left unresolved so that consumers can apply their own resolution.

• Updated dependencies [c6579d3, 444b75e, b38823f, cfd6205, cfd6205]:

  • wrangler@4.103.0
  • miniflare@4.20260617.1

@​cloudflare/vite-plugin@​1.42.0

Minor Changes

• #14339 aa49856 Thanks @​jamesopstad! - Add a build command to the experimental, internal cf-vite delegate binary

  cf-vite build runs Vite's full multi-environment app build (via the Builder API) and enables the experimental Build Output API by default, emitting a self-contained .cloudflare/output/v0/ directory. It forces experimental.newConfig and experimental.newConfig.cfBuildOutput on, so a cloudflare.config.ts is required at the project root.

Patch Changes

• #14346 e930bd4 Thanks @​haidargit! - Bump ws from 8.20.1 to 8.21.0 to address GHSA-96hv-2xvq-fx4p

  GHSA-96hv-2xvq-fx4p / CVE-2026-48779 (high severity) reports a remote memory-exhaustion DoS in ws@<8.21.0: a peer sending a high volume of tiny fragments and data chunks over modest network traffic can crash a ws server or client via OOM. The fix shipped in ws@8.21.0 (commit 2b2abd45, released 2026-05-22), which also introduces the maxBufferedChunks and maxFragments options. This change bumps the workspace catalog entry so that miniflare, wrangler, and @cloudflare/vite-plugin all pick up the patched release.

• #14351 6c7df19 Thanks @​jamesopstad! - Force the experimental new config on by default in the cf-vite dev delegate

• #14218 4eed569 Thanks @​matingathani! - Allow resolve.external containing only Node.js built-ins in Worker environments

  Vitest 4 automatically sets resolve.external to the full list of Node.js built-in modules for non-standard Vite environments via its internal runnerTransform plugin. Previously, the Cloudflare Vite plugin rejected any non-empty resolve.external array, throwing an incompatibility error on startup when used alongside Vitest 4.

  The validation check now allows resolve.external arrays that contain only Node.js built-in module names (both bare fs and node:fs forms). The error is only thrown when resolve.external is true or contains non-built-in package names that would prevent user code from being bundled into the Worker.
