## Overview

### Impact

A vulnerability in Ghost's public donation checkout flow allowed an unauthenticated attacker to obtain full paid gift memberships for a minimal payment. No customer or member data was exposed, and the issue could not be used to steal money from a site or its members.

### Vulnerable versions

This vulnerability is present in Ghost from [v6.27.0](https://github.com/TryGhost/Ghost/releases/tag/v6.27.0) up to [v6.43.1](https://github.com/TryGhost/Ghost/releases/tag/v6.43.1).

### Patches

[v6.44.0](https://github.com/TryGhost/Ghost/releases/tag/v6.44.0) contains a fix for this issue. 

### How to update

For self-hosters using Docker, find [Docker’s official Ghost image on Docker Hub](https://hub.docker.com/_/ghost) and follow the documentation on [updating a Docker-based Ghost instance](https://docs.ghost.org/install/docker#updating-ghost).

For self-hosters using Ghost-CLI, see the documentation for [updating Ghost to the latest version](https://docs.ghost.org/update).

### Workarounds

If upgrading immediately is not possible, you can remove the vulnerable checkout path by disabling the donations feature in Ghost Admin under Settings → Membership → Tips & donations until the upgrade is applied.
