CVE-2025-41253 is a high vulnerability (CVSS 7.5) in Vmware Spring Cloud Gateway Server Webflux, published October 16, 2025. No source lists public exploit code. EPSS puts the chance of exploitation in the next 30 days at 0.48%, the 41st percentile. Fixed in org.springframework.cloud:spring-cloud-gateway-server 4.3.2.
The following versions of Spring Cloud Gateway Server Webflux may be vulnerable to the ability to expose environment variables and system properties to attackers.
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.
