GHSA-xq69-5h5v-x9x4 In Spring for Apache Kafka, overly broad trusted-package matching in header mappers exposes JDK classes to deserialization

• Maven org.springframework.kafka:spring-kafka: >= 4.0.0, < 4.0.6 → fixed in 4.0.6 • Maven org.springframework.kafka:spring-kafka: >= 3.3.0, < 3.3.16 → fixed in 3.3.16 • Maven org.springframework.kafka:spring-kafka: >= 3.2.0, <= 3.2.13 (no fix yet) • Maven org.springframework.kafka:spring-kafka: >= 2.9.0, <= 2.9.13 (no fix yet) • Maven org.springframework.kafka:spring-kafka: <= 2.8.11 (no fix yet)

JsonKafkaHeaderMapper and the deprecated DefaultKafkaHeaderMapper matched type headers against trusted packages using a prefix check, meaning that trusting any package implicitly trusted all of its subpackages. Combined with Jackson's default bean deserialization, a producer could supply crafted header values that caused the consumer to deserialize arbitrary JDK types. Affected versions: Spring for Apache Kafka 4.0.0 through 4.0.5; 3.3.0 through 3.3.15; 3.2.0 through 3.2.13; 2.9.0 through 2.9.13; 2.8.0 through 2.8.11.
