Upgrade org.springframework:spring-core to version 6.2.18, 7.0.7 or higher.
Overview
org.springframework:spring-core is a core package within the spring-framework that contains multiple classes and utilities.
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via static resource resolution. An attacker can cause denial of service by sending crafted requests that are slow to resolve when accessing file-system-backed static resources, causing HTTP connections to remain occupied and exhausting server resources.
Note: This is only exploitable if all the following are true:
The application uses Spring MVC or Spring WebFlux.
Static resources are served from the file system.
The application is running on Windows.
