DefaultJmsHeaderMapper copies all JMS user properties into MessageHeaders without excluding framework-significant names

MEDIUM | AUGUST 20, 2026 | CVE-2026-47880

Description

A producer who can publish to a JMS destination consumed by any Spring Integration JMS inbound component can set String JMS properties named replyChannel, errorChannel, or json__TypeId__ which are copied verbatim into the Spring Integration MessageHeaders. Downstream framework code (AbstractMessageProducingHandler.sendOutput, MessagePublishingErrorHandler.resolveErrorChannel) resolves a String replyChannel/errorChannel header to a Spring bean via BeanFactoryChannelResolver, allowing the attacker to redirect handler output or error messages to any MessageChannel bean in the application context, bypassing the intended flow wiring.
