Description

Spring for GraphQL applications are vulnerable to Unsafe Deserialization when processing paginated GraphQL queries. An attacker can craft a malicious GraphQL request that can lead to Remote Code Execution when the application exposes a paginated (Connection) field and the classpath contains specific classes that can be leveraged during deserialization. Affected versions: Spring for GraphQL 2.0.0 through 2.0.3; 1.4.0 through 1.4.5; 1.3.0 through 1.3.8.
