spring-integration-core is vulnerable to Information Disclosure
82
High Risk
This Affects:
spring-integration-coreTL;DR
spring-integration-core fluxTransform shares a RequestMessageHolder across concurrent messages. When the fluxFunction emits asynchronously, reply headers such as replyChannel, correlationId, and tenant headers can be copied from the newest upstream message. One user's payload can then be delivered on another user's reply channel. The patch isolates request headers per in-flight transformation.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and an IntegrationFlow uses .fluxTransform() with an asynchronous fluxFunction that emits raw payloads.
Background info
spring-integration-core is vulnerable to Information Disclosure in versions 0.0.1 - 7.0.5 and 7.1.0 - 7.1.0.
How to fix this
Upgrade the org.springframework.integration:spring-integration-core library to the patch version.
