A flaw was found in Spring Boot, occurring prominently in Spring MVC with a reverse proxy cache. This issue requires Spring MVC to have auto-configuration enabled and the application to use Spring Boot’s welcome page support, either static or templated, resulting in the application being deployed behind a proxy that caches 404 responses. This issue may cause a denial of service (DoS) attack.
