An application should be considered vulnerable when all the following are true:
* The application is using Spring Cloud Gateway Server Webflux (Spring Cloud Gateway Server WebMVC is not vulnerable).
* An admin or untrusted third party using Spring Expression Language (SpEL) to access environment variables or system properties via routes.
* An untrusted third party could create a route that uses SpEL to access environment variables or system properties if: * The Spring Cloud Gateway Server Webflux actuator web endpoint is enabled via management.endpoints.web.exposure.include=gateway and management.endpoint.gateway.enabled=trueor management.endpoint.gateway.access=unrestricte.
* The actuator endpoints are available to attackers.
* The actuator endpoints are unsecured.
