Summary

The PartEventHttpMessageReader in Spring WebFlux does not enforce the maxPartSize limit when maxInMemorySize is set to -1. This affects Spring Framework versions 7.0.0-7.0.8, 6.2.0-6.2.19, and 6.1.0-6.1.28.

Risk Assessment

This can lead to memory or resource exhaustion, causing application failure. An attacker can send large request parts, bypassing limits.

Recommendation

Update Spring Framework to a patched version. If not possible, avoid setting maxInMemorySize to -1 or apply other size limiting mechanisms.
