## Context Two open Dependabot alerts; this PR fixes one with a parent bump (no resolutions), the other is dismissed with analysis (see below). ## joi RangeError DoS (alert 1437, fixed in joi 18.2.1) `joi@17.13.3`'s only parent is `wait-on@7.2.0` (twenty-sdk devDependency, used purely as a CLI: `yarn start`'s `wait-on tcp:3000` and CI's `wait-on http://localhost:3000/healthz --timeout --interval`). Bumping **wait-on 7.2.0 → 9.0.10** (which depends on `joi ^18.2.1`) evicts joi 17 from the lockfile entirely — no forced ranges. Verified: twenty-sdk builds; wait-on 9 smoke-tested with both invocation shapes used in the repo (`tcp:PORT`, `http://… --timeout --interval`). ## @cyntler/react-doc-viewer TXTRenderer "XSS" (alert 1436) — dismissed as inaccurate CVE-2026-30691 claims arbitrary JS execution via a crafted .txt because TXTRenderer "casts raw data as a ReactNode". Verified against the installed 1.17.1 dist: the renderer is `children: currentDocument?.fileData` where the txt fileLoader produces `fileData` via `FileReader.readAsText` — i.e. **always a string rendered as a React child, which React HTML-escapes**. There is no `dangerouslySetInnerHTML`/eval in the path (the only `dangerouslySetInnerHTML` occurrence in the bundle is styled-components' prop whitelist regex). String children cannot execute script in React; the advisory's premise is wrong, and consistently upstream has published no fix. Alert dismissed as *inaccurate* with this analysis. Longer-term, `@cyntler/react-doc-viewer` remains a liability (stale since 2025-09, already needs an ajv resolution) — replacing it with first-party preview renderers is tracked separately.

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.
