Miggo AIRoot Cause Analysis

The vulnerability stems from unsafe deserialization in Spark's launcher API socket communication. The LauncherServer class's connection handler (ServerConnection.run) would be responsible for reading and deserializing commands. Vulnerable versions use raw ObjectInputStream for deserialization, while patched versions add validation(). The function appears in stack traces when malicious payloads are deserialized during exploitation.
