#901 chore(deps): bump lodash from 4.17.21 to 4.18.1 Pull request opened by dependabot[bot] Bumps lodash from 4.17.21 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.template`lodash/lodash@4.18.0-npm-packages...4.18.1-npm-packages

4.18.0

v4.18.0

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"

.

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
