Bumps undici from 6.24.0 to 6.27.0.

Release notes

Sourced from undici's releases.

v6.27.0

⚠️ Security Release

This release line addresses 4 security advisories.

Action required: Upgrade to undici 6.27.0 or later.

npm install undici@^6.27.0

Note on patched version: the v6 fixes shipped in v6.27.0, not 6.26.0 — v6.26.0 contains only the chunked-EOF fix (#5308) and the version bump, none of the security fixes below.

The v6 line is not affected by the SOCKS5 advisories (GHSA-vmh5-mc38-953g, GHSA-hm92-r4w5-c3mj), the shared-cache disclosure (GHSA-pr7r-676h-xcf6), or the 8.x-only WebSocket regression (GHSA-38rv-x7px-6hhq).

Summary

Advisory CVE Severity (CVSS) Fixed in Fix commit
GHSA-vxpw-j846-p89q CVE-2026-12151 High (7.5) 6.27.0 b7f252e7
GHSA-p88m-4jfj-68fv CVE-2026-9679 Moderate (5.9) 6.27.0 25efa447
GHSA-g8m3-5g58-fq7m CVE-2026-11525 Low (3.7) 6.27.0 25efa447
GHSA-35p6-xmwp-9g52 CVE-2026-6733 Low (3.7) 6.27.0 f4c31d60

High severity

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

GHSA-vxpw-j846-p89q · CWE-400, CWE-770 Fix: b7f252e7 Backport WebSocket maxPayloadSize fixes (#5423, backported to v6 in #5428)

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. All releases from 6.17.0 onward are affected.

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

Moderate severity

HTTP header injection via Set-Cookie percent-decoding — CVE-2026-9679

Looks like this PR has been edited by someone other than Dependabot. That means Dependabot can't rebase it - sorry!

If you're happy for Dependabot to recreate it from scratch, overwriting any edits, you can request @dependabot recreate.

A newer version of undici exists, but since this PR has been edited by someone other than Dependabot I haven't updated it. You'll get a PR for the updated version as normal once this PR is merged.
