CVE-2021-22053: VMware Spring Cloud Netflix

High severity, CVSS 8.8. EPSS: 13.2% chance of exploitation in the next 30 days.

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.

Affected products

• VMware Spring Cloud Netflix: from 2.2.0, before 2.2.10 (fixed in 2.2.10)
