GraphQL complexity calculation does not enforce adequate resource allocation limits. An unauthenticated user can submit queries that exhaust resources and cause denial of service. The fix tightens GraphQL complexity limiting so oversized queries are rejected before they can overwhelm the instance.

You are affected if you are using a version that falls within the vulnerable range.
