Description

SerializingHttpMessageConverter deserializes the body of incoming HTTP requests with a raw java.io.ObjectInputStream and no class filtering. Any request with Content-Type application/x-java-serialized-object whose body resolves to a Serializable type is read directly via readObject(). If an application using this converter on an inbound HTTP endpoint has any known Java deserialization "gadget" on its classpath, a remote, unauthenticated attacker can achieve arbitrary code execution.
