Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
GraphQL Java (aka graphql-java) before 21.5 does not properly consider ExecutableNormalizedFields (ENFs) as part of preventing denial of service via introspection queries. 20.9 and 19.11 are also fixed versions.
