State: Published
Severity: 6.5 Medium
Published: Apr 29, 2026
Updated: Apr 29, 2026
Reserved: Jan 9, 2026

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.

Older, unsupported versions are also affected.
