python-kwargs-setattr-security Skill
When reviewing or fixing Python code that uses setattr() with user-controlled kwargs to configure C++ extension objects (SessionOptions, RunOptions, etc.) in ONNX Runtime. Use this to apply the allowlist pattern that prevents arbitrary file writes and other attacks via reflected property access. Published by microsoft in onnxruntime.

Skill instructions
Problem Pattern Using hasattr(obj, k) / setattr(obj, k, v) with user-controlled kwargs is insecure. The hasattr check is NOT a security guard — it returns True for ALL exposed properties including dangerous ones. python INSECURE — do not use for k, v in kwargs.items(): if hasattr(options, k): setattr(options, k, v) Fix: Explicit Allowlist Define a module-level frozenset of safe attribute names. Raise RuntimeError for known-but-blocked attrs; silently ignore unknown keys. python Define at module level, before the class ALLOWEDSESSIONOPTIONS = frozenset({ "enablecpumemarena", "enablemempattern", ... only explicitly reviewed safe attrs }) In the method for k, v in kwargs.items(): if k in ALLOWEDSESSIONOPTIONS: setattr(options, k, v) elif hasattr(options, k): reuse the existing instance, don't create new raise RuntimeError( f"SessionOptions attribute '{k}' is not permitted via the backend API. " f"Allowed attributes: {', '.join(sorted(ALLOWEDSESSIONOPTIONS))}" ) else: silently ignore (may
