CVE-2026-47856: Deserialization of Untrusted Data

Spring Integration's JSON to object conversion uses the jsonTypeId header to choose the deserialization target type, and resolves that header value to a class with ClassUtils.forName and no type/package allow-list. Spring Integration 7.1.0 Spring Integration 7.0.0 - 7.0.5 Spring Integration 6.5.0...

CVE-2026-47861: Server-Side Request Forgery (SSRF)

An unauthenticated remote attacker who can send a single UDP packet to a Spring Integration UDP inbound adapter can cause the server to emit an outbound UDP datagram to an arbitrary internal or external host and port of the attacker's choosing. Spring Integration 7.1.0 Spring Integration 7.0.0 -...
