CVE-2025-32031Network attack vector

Unauthenticated service hang via query-planner optimization bypass

Published Apr 7, 2025 · Updated Apr 8, 2025

Denial of service in Apollo Gateway before 2.10.1 allows remote attackers to hang the gateway with crafted GraphQL queries. Deeply nested, repeatedly reused named fragments generate selections that bypass the query planner's skip optimization, while planning has no timeout. Unauthenticated access to the GraphQL endpoint is sufficient; a small number of requests can consume resources until the gateway becomes inoperable.
