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) are vulnerable to denial of service when resolving static resources, in 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. The issue affects applications that serve static resources from the file system on Windows. An attacker who can send requests to the application can make slow-to-resolve requests that hold HTTP connections, causing a denial of service. Upgrade to spring-webmvc or spring-webflux 7.0.7 or 6.2.18, or the fixed release in your branch.
