Spring for GraphQL's Spring Data pagination support resolves arguments of a scrollable query and forwards the client-supplied values to the underlying repository. An attacker can forge a malicious query for a Connection field that can exhaust application memory or place significant, prolonged load on the underlying datastore, resulting in a Denial of Service. Spring for GraphQL 2.0.0 - 2.0.4 Spring for GraphQL 1.4.0 - 1.4.6 Spring for GraphQL 1.2.0 - 1.3.9

A batch loader function in Spring for GraphQL versions 1.1.0 - 1.1.5 and 1.2.0 - 1.2.2 may be exposed to GraphQL context with values, including security context values, from a different session. An application is vulnerable if it provides a DataLoaderOptions instance when registering batch loader functions through DefaultBatchLoaderRegistry.
