CVE-2026-47880Network attack vector

Message redirection via unfiltered JMS properties

Published Aug 27, 2026 · Updated Aug 27, 2026

Improper input validation in Spring Integration allows remote authenticated users to redirect handler output through crafted JMS properties. DefaultJmsHeaderMapper copies replyChannel, errorChannel, and json__TypeId__ user properties into MessageHeaders without excluding framework-reserved names. Access to publish to a consumed JMS destination is required; downstream resolvers treat attacker-selected channel names as bean references, enabling output or error-message redirection within the application.
