  "details" : [ "A flaw was found in Spring MVC and Spring WebFlux applications. A remote attacker can exploit this vulnerability by sending malicious requests to poison the resource cache with incorrectly encoded resources. This can lead to a denial of service (DoS) by disrupting the front-end application for clients. This vulnerability occurs when the application uses resource chain support with caching enabled, supports encoded resource resolution, and the resource cache is empty." ],
