CVE-2025-33214Network attack vector

Code execution via unsafe workflow deserialization

Published Dec 9, 2025 · Updated Dec 9, 2025

Deserialization in NVIDIA NVTabular Workflow on Linux allows remote attackers to execute code through a malicious workflow file. Workflow.load passes workflow.pkl from the supplied path directly to cloudpickle.load, allowing pickle data to import and invoke attacker-chosen Python objects. Exploitation requires a user to load an attacker-controlled workflow; code runs in that user's process and can read, alter, or crash accessible resources.
