Warning

Data binding can lead to security issues by exposing parts of the object graph that are not meant to be accessed or modified by external clients. Therefore the design and use of data binding should be considered carefully with regard to security. For more details, please refer to the dedicated sections on data binding for Spring Web MVC and Spring WebFlux in the reference manual.
