## 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.
Self Hosting
The Self Hosting app collects sign-up telemetry from self-hosted Twenty instances and turns it into structured CRM records. Each time a user signs up on a self-hosted instance, the app records who they are, which instance they belong to, and automatically links them to a matching Person in your workspace.
What it does
- Receives sign-up events from self-hosted instances through a public telemetry webhook.
- Creates or updates a Self Hosting User record for each real sign-up, keyed by email address.
- Automatically matches every Self Hosting User to an existing Person by email, creating a new Person when none is found, and keeps that link up to date as the data changes.
- Filters out test and example sign-ups so they never enter your CRM.
- Carries a rich set of person and company enrichment fields so each sign-up can be augmented with firmographic data.
What it adds to your workspace
Self Hosting User object
A new object, Self Hosting Users, stores one record per self-hosted sign-up. Its fields include:
- Identity: Name, Email, Domain, Locale. The webhook only populates Name, Email, and Locale; Domain exists on the object but is not filled in by the sign-up flow.
- Instance: Server URL, Server ID, User ID, User Workspace ID.
- Relations: Person, the matched standard Person record for this user.
- Aggregate: Number of Emails with Same Domain, a count of users sharing the same business domain. This field is part of the data model but is not populated by the app's own ingestion or matching logic.
- Enrichment state: Is Enriched, Tried To Be Enriched, Is Personal Email, Is Twenty.
- Person enrichment: City, Country, Job Function, Job Title, LinkedIn, Seniority.
- Company enrichment: Name, Description, Industry, Industries, Employees, Founded Year, Annual Revenue, Funding Latest Stage, Funding Total Amount, Alexa Rank, LinkedIn, Tags, Tech.
Person relation
The standard Person object gains a Self hosting users relation, so you can see every self-hosted sign-up tied to a given person directly from their record.
View and navigation
A Self hosting users table view exposes all of the fields above as columns and is added to the left sidebar for quick access.
Role
The app ships a default role with read, update, and soft-delete permissions over workspace records. Permanent deletion is not granted.
How sign-up data flows in
The app exposes an unauthenticated HTTP endpoint that self-hosted instances post telemetry to:
- Method:
POST - Path:
/webhook/telemetry
A request is processed only when its action is user_signup; any other event type is acknowledged and ignored. The payload carries the user's email, first and last name, locale, the originating server URL and server ID, and workspace identifiers.
When a valid sign-up arrives:
- Non-signup events are acknowledged and ignored first; then sign-ups with no email are skipped; then sign-ups whose email contains
testorexample(case-insensitive) are ignored. - If a Self Hosting User already exists for that email, it is updated with the latest details; otherwise a new one is created. The app persists Name, Email, Locale, Server URL, Server ID, User ID, and User Workspace ID; Domain and the enrichment fields are left for separate processes.
- Whenever a Self Hosting User is created or its email changes, the app looks for a Person with the same email. If one exists it links them; if not, it creates a Person and links it. Records that already have a matched Person and an unchanged email are left untouched.
Configuration
This app requires no server or application variables. To send data into it, point a self-hosted Twenty instance's telemetry at the webhook path above on the workspace where this app is installed.
Limitations
- The telemetry webhook is intentionally unauthenticated and performs no signature or shared-secret verification. Any client that can reach the endpoint can submit sign-up events, so it should only be exposed to trusted self-hosted instances.
- Test/example filtering is a simple substring match: any email containing
testorexampleanywhere is excluded, even if it is a legitimate address. - The enrichment fields and the Domain field are part of the data model but are populated by separate processes; the app itself ingests sign-ups and performs Person matching.
