Improper Privilege Management
When Spring MVC or Spring WebFlux server application (server A) receives input from a remote client, and then uses that input to make a multipart request to another server (server B), it can be exposed to an attack, where an extra multipart is inserted in the content of the request from server A, causing server B to use the wrong value for a part it expects. This could to lead privilege escalation, for example, if the part content represents a username or user roles.

Uncontrolled Resource Consumption
Spring Framework provides support for range requests when serving static resources through the `ResourceHttpRequestHandler`. A malicious user (or attacker) can add a range header with a high number of ranges, or with wide ranges that overlap, or both, for a denial of service attack.

Path Traversal
Spring Framework allows applications to configure Spring MVC to serve static resources (e.g., CSS, JS, images). When static resources are served from a file system on Windows (as opposed to the classpath, or the `ServletContext`), a malicious user can send a request using a specially crafted URL that can lead a directory traversal attack.
