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 up to v6.43.1.
Patches
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 and follow the documentation on updating a Docker-based Ghost instance.
For self-hosters using Ghost-CLI, see the documentation for updating Ghost to the latest version.
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.
