Medium (5.3) in vmware spring cloud netflix zuul. EPSS 0.9% chance of exploitation in the next 30 days. Fixed in org.springframework.cloud:spring-cloud-netflix-zuul 2.2.7.

Applications using the “Sensitive Headers” functionality in Spring Cloud Netflix Zuul 2.2.6.RELEASE and below may be vulnerable to bypassing the “Sensitive Headers” restriction when executing requests with specially constructed URLs. Applications that use Spring Security's StrictHttpFirewall (enabled by default for all URLs) are not affected by the vulnerability, as they reject requests that allow bypassing.
