CVE-2026-47707Public exploitNetwork attack vector

Service interruption via fragment-spread alias amplification

Published Jun 4, 2026 · Updated Jun 4, 2026

Uncontrolled resource consumption in Strawberry GraphQL 0.172.0 through 0.315.6 allows remote attackers to interrupt service via GraphQL queries. MaxAliasesLimiter statically counts aliases in a fragment once instead of multiplying them by each FragmentSpreadNode use, so execution resolves far more aliases than the configured limit. A remotely reachable GraphQL endpoint must enable this extension; crafted queries then consume excessive CPU and memory and interrupt only the affected application.
