CVE-2025-32030

Apollo Gateway provides utilities for combining multiple GraphQL microservices into a single GraphQL endpoint. Prior to 2.10.1, a vulnerability in Apollo Gateway allowed queries with deeply nested and reused named fragments to be prohibitively expensive to query plan, specifically during named fragment expansion. Named fragments were being expanded once per fragment spread during query planning, leading to exponential resource usage when deeply nested and reused fragments were involved. This could lead to excessive resource consumption and denial of service. This has been remediated in @apollo/gateway version 2.10.1.

Impact

Summary

A vulnerability in Apollo Gateway allowed queries with deeply nested and reused named fragments to be prohibitively expensive to query plan, specifically during named fragment expansion. This could lead to excessive resource consumption and denial of service.

Details

Named fragments were being expanded once per fragment spread during query planning, leading to exponential resource usage when deeply nested and reused fragments were involved.

Fix/Mitigation

A new Query Fragment Expansion Limit metric has been introduced:

• This metric computes the number of selections a query would have if its fragment spreads were fully expanded.
• The metric is checked against a limit to prevent excessive computation.

Patches

This has been remediated in @apollo/gateway version 2.10.1.

Workarounds

No known direct workarounds exist.
