The vulnerability stems from unsafe Java deserialization in two key locations: 1) DefaultDeserializer's core deserialization method lacked validation(), and 2) SimpleMessageConverter's message deserialization path used raw ObjectInputStream. The security patch added whitelist validation() to both locations. These functions would appear in stack traces when processing malicious AMQP messages containing serialized gadget chains.
