      "value": "A WebFlux server application that processes multipart requests creates temp files for parts larger than 10 K. Under some circumstances, temp files may remain not deleted after the request is fully processed. This allows an attacker to consume available disk space.\n\nOlder, unsupported versions are also affected."

Bajo ciertas circunstancias, los archivos temporales pueden permanecer sin eliminar después de que la solicitud se haya procesado completamente.
