CVE-2025-33183Network attack vector

Unauthenticated code execution via unsafe Torch deserialization

Published Nov 18, 2025 · Updated Nov 18, 2025

Deserialization of untrusted data in NVIDIA Isaac GR00T N1.5 allows remote attackers to execute arbitrary code without authentication. The TorchSerializer.from_bytes method passes network-supplied bytes to torch.load with weights_only=False, permitting pickle payloads to instantiate attacker-controlled objects. A network client that can reach the inference service can execute code in the server process context, which ZDI reports can be root.
