build(deps): bump lodash from 4.17.21 to 4.18.1 in /catalog

[dependabot]

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.templatelodash/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".

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

Greptile Summary

This PR bumps lodash from 4.17.21 to 4.18.1 in the catalog package, addressing two security vulnerabilities included in the 4.18.0 release:

• GHSA-f23m-r3pf-42rh — Prototype pollution via constructor/prototype path traversal in _.unset / _.omit
• GHSA-r5fr-rjxr-66jc (CVE-2026-4800) — Code injection via unsanitized imports keys in _.template, an incomplete fix for CVE-2021-23337

The change is confined to catalog/package.json (version range bump) and catalog/package-lock.json (resolved version and integrity hash). No source files were modified.

Notable observation: Two nested, dev-only lodash copies introduced by graphql tooling remain on older versions in the lock file:

• @graphql-codegen/plugin-helpers → lodash@4.17.23 (dev)
• @graphql-tools/url-loader → lodash@4.17.21 (dev)

Because both are dev: true, they are excluded from the production bundle and pose no runtime risk to end users.

Confidence Score: 5/5

Safe to merge — purely a security patch dependency bump with no source changes.

The PR only modifies lock and manifest files to upgrade lodash from 4.17.21 to 4.18.1, which ships two confirmed security fixes. The integrity hash is present, the change is generated by Dependabot, and no application logic is touched. The remaining older lodash copies are dev-only and excluded from the production bundle.

No files require special attention, but catalog/package-lock.json contains two dev-only nested lodash copies still on older versions (4.17.21 and 4.17.23) — worth tracking for a future cleanup if those transitive dev dependencies are ever updated.

Important Files Changed

Filename	Overview
catalog/package.json	Version range for lodash updated from ^4.17.21 to ^4.18.1 — straightforward and correct.
catalog/package-lock.json	Top-level lodash resolved to 4.18.1 with updated integrity hash; two dev-only nested copies (@graphql-codegen/plugin-helpers → 4.17.23, @graphql-tools/url-loader → 4.17.21) remain on older, unpatched versions but are excluded from the production build.

Looks like lodash is updatable in another way, so this is no longer needed.
