…e during JSON deserialization Event, SegmentRange and BroadcastEventReadyNotifier use @JsonTypeInfo(Id.CLASS), which lets an attacker-supplied @Class id load arbitrary classes (deserialization gadget attack). Set a BasicPolymorphicTypeValidator that only allows org.apache.kylin.* subtypes on the JsonUtil mappers and on the Spring HTTP converter ObjectMapper in AppConfig.
