Description
In Spring Framework versions 6.0.0 - 6.0.13, it is possible for a user to provide specially crafted HTTP requests that may cause a denial-of-service (DoS) condition.
Specifically, an application is vulnerable when all of the following are true:
* the application uses Spring MVC or Spring WebFlux
* io.micrometer:micrometer-core is on the classpath
* an ObservationRegistry is configured in the application to record observations
Typically, Spring Boot applications need the org.springframework.boot:spring-boot-actuator dependency to meet all conditions.
