Vulnerability details

The vulnerability allows an unauthenticated remote attacker to read entry content excluded from a Craft CMS GraphQL schema.

The vulnerability exists due to missing section-scope authorization in GraphQL prev/next traversal when a public schema or scoped private token exposes one section but withholds another sharing its entry type. An unauthenticated remote attacker can obtain a visible entry’s ID through a root query and chain next hops to enumerate entries and retrieve withheld custom-field content.
