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 spring_json_header_types message header. Spring for Apache Kafka 4.1.0 Spring for Apache Kafka 4.0.0 - 4.0.6 Spring for Apache Kafka 3.0.0 - 3.3.16 Spring for Apache Kafka 2.9.0 - 2.9.14 Spring for Apache Kafka 2.8.12 and earlier
AnalysisAI
Header type injection in Spring for Apache Kafka's default mapper configuration allows any Kafka producer with access to a consumed topic to inject java.net.InetAddress objects through the spring_json_header_types message header, triggering DNS resolution on the consumer host. All applications using @KafkaListener with the default JsonKafkaHeaderMapper or DefaultKafkaHeaderMapper - spanning versions 2.8.x through 4.1.0 - are affected without any non-default configuration required. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Three concrete conditions must hold simultaneously: the target application must use @KafkaListener consumers (the idiomatic Spring Kafka pattern); must use JsonKafkaHeaderMapper or DefaultKafkaHeaderMapper without an explicit setTrustedPackages() call that excludes java.net (the default for all Spring Kafka consumers - no misconfiguration required); and the attacker must have the ability to produce messages to a Kafka topic the target application is subscribed to. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 6.5 Medium score (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N) reflects a broadly exploitable surface: any party able to produce messages to a Kafka topic the target subscribes to can trigger the flaw with no authentication and minimal complexity. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the vendor-released patch by upgrading Spring for Apache Kafka to a fixed version as detailed in the Spring security advisory at https://spring.io/security/cve-2026-59278; no specific fixed version number is confirmed in the available intelligence and should be verified directly against the advisory. … Detailed patch versions, workarounds, and compensating controls in full report. |
