What it is

Craft CMS before 5.11.0 fails to enforce user-group scope filters on native GraphQL user relations including author, authors, uploader, draftCreator, and revisionCreator fields. Attackers with a scoped GraphQL token can query these relations to read usernames, email addresses, and full names of any content author or uploader including administrators.
