Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Spring MVC (spring-webmvc) and Spring WebFlux (spring-webflux) versions 7.0.0 to before 7.0.7, 6.2.0 to before 6.2.18, 6.1.0 through 6.1.26, and 5.3.47 and earlier are affected. An attacker with network access can send crafted requests to poison the static resource cache, but only when resource chain caching is enabled, encoded resource resolution has been added, and the cache is empty. The result is a denial of service that breaks the front-end application for clients. Upgrade to spring-webmvc or spring-webflux 7.0.7 or 6.2.18; no fix is listed for the 6.1.x or 5.3.x lines.
