spring-cloud-stream is vulnerable to Improper Access Control
31
Low Risk
This Affects:
spring-cloud-streamTL;DR
spring-cloud-stream can attach a partition interceptor to the wrong send path. Messages may then be partitioned or observed by logic that should not run for that destination. A high-privilege sender with a specific send pattern can trigger the mis-wiring. The patch adds partition interceptors only to the intended channel.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and partition interceptors are added while sending messages.
Background info
spring-cloud-stream is vulnerable to Improper Access Control in versions 4.2.0 - 5.0.2.
How to fix this
Upgrade the org.springframework.cloud:spring-cloud-stream library to the patch version.
