spring-amqp-client is vulnerable to Denial of Service (DoS)
65
Medium Risk
This Affects:
spring-amqp-clientTL;DR
spring-amqp-client never replenishes link credit when a container-level ErrorHandler handles a listener exception. After the default 100 credits are consumed by failing deliveries, the broker stops sending while isRunning() remains true. The listener then stalls silently. The patch restores credit on the exception path.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and a container-level ErrorHandler is configured on a Spring AMQP listener.
Background info
spring-amqp-client is vulnerable to Denial of Service (DoS) in versions 4.1.0 - 4.1.0.
How to fix this
Upgrade the org.springframework.amqp:spring-amqp-client library to the patch version.
