Justification. The vulnerability can be exploited only when an application uses the Spring MVC functional web framework (RouterFunction) to send Server-Sent Events with ServerResponse.sse(). Higson Studio 4.2 and Higson Runtime REST 4.2 define no RouterFunction routes and expose no Server-Sent Events endpoints. The vulnerable code is shipped with the library but is never executed.
