Overview
About vulnerability
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, including classes whose constructors carry side effects such as allocating file descriptors or spawning thread pools.
