Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Spring Framework spring-webmvc versions 6.0.0 through 6.0.13 are vulnerable to a denial-of-service condition. A remote user can send specially crafted HTTP requests to cause the service to stop responding, but only when the application uses Spring MVC or WebFlux, has io.micrometer:micrometer-core on the classpath, and has an ObservationRegistry configured. Upgrade spring-webmvc to 6.0.14.
