CVE-2024-28424Network attack vector

Code execution via unsafe cloudpickle deserialization

Published Mar 14, 2024 · Updated Apr 10, 2025

Arbitrary code execution in ZenML 0.55.4 allows remote attackers to run crafted Python payloads through a cloudpickle artifact. CloudpickleMaterializer.load opens the stored artifact and passes its attacker-controlled bytes to cloudpickle.load, which reconstructs executable Python objects. Exploitation requires the crafted artifact to be loaded by a workflow, after which code runs with the pipeline process's privileges.
