spring-webflux is vulnerable to Denial of Service (DoS)
43
Medium Risk
This Affects:
spring-webfluxTL;DR
spring-webflux Jaxb2Decoder does not enforce maxInMemorySize when parsing XML with the Aalto processor. A client can send a large XML body and bypass the configured memory limit. That can exhaust heap on the decoder path. The patch applies maxInMemorySize to Aalto-backed XML decoding.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and WebFlux XML decoding uses the Aalto processor via Jaxb2Decoder.
Background info
spring-webflux is vulnerable to Denial of Service (DoS) in versions 0.0.1 - 7.0.8.
How to fix this
Upgrade the org.springframework:spring-webflux library to the patch version.
