## Summary Bumps **postcss -> 8.5.22** in the 13 twenty-apps lockfiles that carry it transitively, clearing **GHSA-r28c-9q8g-f849** (high) on those manifests: path traversal in previous source map auto-loading (`sourceMappingURL`) leading to arbitrary `.map` file disclosure, vulnerable `<= 8.5.17`. Apps covered: document-generator, hello-world, postcard, self-hosting, twenty-partners, call-recorder, people-data-labs, twenty-discord, twenty-exa, twenty-fireflies, twenty-last-contact, twenty-linear, twenty-slack. Every app reaches postcss through a caret range (`^8.5.15`), so a recursive `yarn up -R postcss` lifts it in each project with **no resolution and no `package.json` change** - the diff is 13 `yarn.lock` files and nothing else. Yarn resolves to **8.5.22**, the latest in range (above the 8.5.18 fix floor). ## Not included The **root lockfile** carries the same advisory but its postcss copies are held by exact pins - `next` (8.4.31 in every stable release, including 16.2.11) and `@mintlify/common` (8.5.14, unchanged in its latest) - so no `yarn up` reaches it. That one needs a scoped resolution and is handled separately. ## Verification - postcss resolves to **8.5.22** in all 13 lockfiles; nothing at or below 8.5.17 remains. - `yarn install --immutable` passes in each of the 13 projects. - 8.5.22 published 2026-07-22, clears the 3-day npm age gate.

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.
