## Summary Resolves [Dependabot alert #1504](https://github.com/twentyhq/twenty/security/dependabot/1504) — js-yaml **CVE-2026-53550 / GHSA-h67p-54hq-rp68** (quadratic-complexity DoS in YAML merge-key handling, vulnerable `<=4.1.1`, fixed `4.2.0`) — by lifting the vulnerable **js-yaml 4.1.1 → 4.2.0**. ## Why scoped resolutions (not a global pin) - js-yaml 4.1.1 is held alive by **7 packages that hard-pin it exact** (no caret, still 4.1.1 in their latest): `@mintlify/{cli,common,prebuild,previewing,scraping,validation}` + `@verdaccio/config`. No parent upgrade carries the fix, so each is scoped to 4.2.0 — matching the repo's `parent/child` convention. - The 5 alert paths (`@graphql-codegen/cli`, `@lingui/cli`, `@lingui/vite-plugin`, `@wyw-in-js/vite`, `vite-plugin-svgr`) only *shared* that 4.1.1 via `cosmiconfig` (`^4.1.0`) — once the exact pins are lifted, they **dedupe onto 4.2.0 on their own**. - Forcing 4.1.1 → 4.2.0 is a **safe minor** (same 4.x `.load` API; the fix just bounds merge-key complexity). ## The js-yaml 3.x remnant (deliberately left) `front-matter@4.0.2` (via mintlify) and `@istanbuljs/load-nyc-config@1.1.0` (via storybook coverage) declare `js-yaml ^3.13.1 → 3.14.2`. **front-matter calls the `safeLoad` API that js-yaml 4.x removed**, so it cannot take 4.2.0 — a global pin would break it (which is why this is scoped). That 3.x copy is left in place; both parse only **first-party trusted YAML** (nycrc + docs front-matter), so the merge-key DoS isn't reachable. If Dependabot still flags that 3.x copy, it's a dismiss candidate (no safe transitive fix — front-matter is EOL on the `safeLoad` API). ## Verification - `yarn install --immutable` passes. - No `js-yaml@4.1.1` remains; js-yaml is now `4.2.0` (+ the documented `3.14.2` remnant). - Diff is js-yaml-only; matching `"//resolutions"` doc entry included.

Installation
Cloud
The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.
Build an app
Scaffold a new app with the Twenty CLI:
npx create-twenty-app my-app
Define objects, fields, and views as code:
import { defineObject, FieldType } from 'twenty-sdk/define';
export default defineObject({
nameSingular: 'deal',
namePlural: 'deals',
labelSingular: 'Deal',
labelPlural: 'Deals',
fields: [
{ name: 'name', label: 'Name', type: FieldType.TEXT },
{ name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
{ name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
],
});
Then ship it to your workspace:
npx twenty app:publish --private
See the app development guide for objects, views, agents, and logic functions.
Self-hosting
Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
Everything you need
Twenty gives you the building blocks of a modern CRM (objects, views, workflows, and agents) and lets you extend them as code. Here's a tour of what's in the box.
