CVE-2026-59817

Ghost is a Node.js content management system. From 6.27.0 before 6.44.0, Ghost's public donation checkout flow allowed an unauthenticated attacker to control donation checkout metadata and obtain full paid gift memberships for a minimal payment without exposing customer or member data or stealing money from a site or its members. This issue is fixed in version 6.44.0.
