Maintainer changes

This version was pushed to npm by ljharb, a new releaser for form-data since your current version.

Install script changes

This version modifies prepublish script that runs during installation. Review the package contents before updating.

Updates 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.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
