CVE-2024-43414Network attack vector

Gateway crash via unbounded query-plan enumeration

Published Aug 27, 2024 · Updated Aug 27, 2024

Denial of service in Apollo Federation components allows remote attackers to crash affected gateways with sufficiently complex queries. The query planner multiplies candidate counts until the value becomes Infinity, then fails to prune alternatives and enumerates plans without bound. Exploitation requires a non-key field resolvable by multiple subgraphs and can exhaust memory until the gateway crashes or is terminated.
