ghost is a publishing platform
Affected versions of this package are vulnerable to Insertion of Sensitive Information Into Sent Data via the Admin API, which returns API keys to authenticated low-privilege staff users who should not have access to them. These keys are intended to be restricted to higher-privileged users, but insufficient access controls allow any staff-level authenticated user to read them through standard Admin API responses.
