CVE-2026-59278 In Spring for Apache Kafka, SSRF via DNS resolution triggered by untrusted java.net types in header mapper default trusted packages

JsonKafkaHeaderMapper and DefaultKafkaHeaderMapper include java.net in their default trusted packages list. When these mappers are used — which is the default configuration for all @KafkaListener consumers — an external Kafka producer can inject a java.net.InetAddress type via the...
