| Doc Text: |
A flaw was found in Spring WebFlux, a component of the Spring Framework. A remote attacker can exploit this vulnerability by sending specially crafted multipart requests to a WebFlux server application. When processing these requests, the server creates temporary files that, under certain conditions, are not properly deleted. This can lead to an accumulation of temporary files, consuming available disk space and potentially causing a Denial of Service (DoS) for the affected system.
