Updates undici from 7.27.2 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: 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 js-yaml from 4.1.0 to 4.3.0

Changelog

Sourced from js-yaml's changelog.

4.3.0, 3.15.0 - 2026-06-27

Security

• Backported maxTotalMergeKeys option.

[5.2.0] - 2026-06-26

Added

• Added maxTotalMergeKeys (10000) loader option to limit the total number of keys processed by YAML merge (<<) across one load() / loadAll() call.
• Added maxAliases (-1) loader option to limit the number of YAML aliases per document.

Removed

• maxMergeSeqLength replaced with maxTotalMergeKeys for limiting YAML merge processing.

Fixed

• Round-trip of integers with exponential form (>= 1e21)

[5.1.0] - 2026-06-23

Added

• Collection tags can finalize an incrementally populated carrier into a different result value.

Changed

• [breaking] quoteStyle now selects the preferred quote style; use the restored forceQuotes option to force quoting non-key strings.

[5.0.0] - 2026-06-20

Added

• Added named exports for schemas, tags, parser events and AST utilities.
• Reworked JSON_SCHEMA and CORE_SCHEMA with spec-compliant scalar resolution rules, and added YAML11_SCHEMA.
• Added realMapTag for lossless mappings with non-string and complex keys. Object-based mappings now reject complex keys instead of stringifying them.
• Added dump() transform option for changing the generated AST before rendering.
• Added dump() options seqInlineFirst, flowBracketPadding, flowSkipCommaSpace, flowSkipColonSpace, quoteFlowKeys, quoteStyle and tagBeforeAnchor.
• Added formal data layers (events and AST) for modular data pipelines.
  • Added low-level parser (to events), presenter and visitor APIs.
• Added the YAML Test Suite to the test set.

Changed

• See the migration guide for upgrade notes.
• Rewritten in TypeScript and reorganized the public API around flat named exports.

Updates lodash from 4.17.23 to 4.18.1

Release notes

Sourced from lodash's releases.

4.18.1

Bugs

Fixes a ReferenceError issue in lodash lodash-es lodash-amd and lodash.template when using the template and fromPairs functions from the modular builds. See lodash/lodash#6167

These defects were related to how lodash distributions are built from the main branch using https://github.com/lodash-archive/lodash-cli. When internal dependencies change inside lodash functions, equivalent updates need to be made to a mapping in the lodash-cli. (hey, it was ahead of its time once upon a time!). We know this, but we missed it in the last release. It's the kind of thing that passes in CI, but fails bc the build is not the same thing you tested.

There is no diff on main for this, but you can see the diffs for each of the npm packages on their respective branches:

• lodash: lodash/lodash@4.18.0-npm...4.18.1-npm
• lodash-es: lodash/lodash@4.18.0-es...4.18.1-es
• lodash-amd: lodash/lodash@4.18.0-amd...4.18.1-amd
• lodash.templatelodash/lodash@4.18.0-npm-packages...4.18.1-npm-packages

4.18.0

v4.18.0

Full Changelog: lodash/lodash@4.17.23...4.18.0

Security

_.unset / _.omit: Fixed prototype pollution via constructor/prototype path traversal (GHSA-f23m-r3pf-42rh, fe8d32e). Previously, array-wrapped path segments and primitive roots could bypass the existing guards, allowing deletion of properties from built-in prototypes. Now constructor and prototype are blocked unconditionally as non-terminal path keys, matching baseSet. Calls that previously returned true and deleted the property now return false and leave the target untouched.

_.template: Fixed code injection via imports keys (GHSA-r5fr-rjxr-66jc, CVE-2026-4800, 879aaa9). Fixes an incomplete patch for CVE-2021-23337. The variable option was validated against reForbiddenIdentifierChars but importsKeys was left unguarded, allowing code injection via the same Function() constructor sink. imports keys containing forbidden identifier characters now throw "Invalid imports option passed into _.template".

Docs

• Add security notice for _.template in threat model and API docs (#6099)
• Document lower > upper behavior in _.random (#6115)
• Fix quotes in _.compact jsdoc (#6090)

lodash.* modular packages

Diff

We have also regenerated and published a select number of the lodash.* modular packages.

These modular packages had fallen out of sync significantly from the minor/patch updates to lodash. Specifically, we have brought the following packages up to parity w/ the latest lodash release because they have had CVEs on them in the past:

• lodash.orderby
• lodash.tonumber
• lodash.trim
• lodash.trimend
• lodash.sortedindexby
• lodash.zipobjectdeep
• lodash.unset
• lodash.omit
• lodash.template

... (truncated)

Changelog

Sourced from immutable's changelog.

5.1.9

• fix(List): a List grown past 32 elements while all its values are undefined no longer reads those values back as null (affected get, iteration, toArray, equals and hashCode)

5.1.8

• fix(List): guard oversized bounds in setListBounds. Fixes CVE GHSA-v56q-mh7h-f735
• perf(Map): index large hash-collision buckets for faster lookups. Fixes CVE GHSA-xvcm-6775-5m9r

4.3.9

• fix(List): guard oversized bounds in setListBounds. Fixes CVE GHSA-v56q-mh7h-f735
• perf(Map): index large hash-collision buckets for faster lookups. Fixes CVE GHSA-xvcm-6775-5m9r

5.1.7

• fix(Repeat): lastIndexOf returned size instead of size - 1 by @​chatman-media in immutable-js/immutable-js#2227. Fixes CVE CVE-2026-29063
• fix(IndexedCollection): has(index) on a lazy Seq of unknown size now checks index existence instead of searching for a value equal to the index #2203
• [TypeScript]: reduce/reduceRight without an initial value now infer the result type from the collection's values when the reducer returns a value (e.g. list.reduce((a, b) => a + b) infers number), matching Array#reduce. Previously an explicit type argument was required. #2205

5.1.6
