Spring Security Advisory
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-coreis 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.
