Applications using both `spring-cloud-netflix-hystrix-dashboard` and `spring-boot-starter-thymeleaf` expose a way to execute code submitted within the request URI path during the resolution of view templates. When a request is made at `/hystrix/monitor;[user-provided data]`, the path elements following `hystrix/monitor` are being evaluated as SpringEL expressions, which can lead to code execution.
