Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
GraphQL Java (com.graphql-java:graphql-java) versions before 19.11, from 20.0 before 20.9, and from 21.0 before 21.5 do not properly account for ExecutableNormalizedFields when guarding against denial of service through introspection queries. The source does not describe the attacker's required access or the exact effect beyond denial of service. Upgrade to 19.11, 20.9, 21.5, or a later version in the matching release line.
