CVE-2026-68772
ZenML 0.94.6 Remote Code Execution via CloudpickleMaterializer
ZenML 0.94.6 contains a remote code execution vulnerability in the CloudpickleMaterializer component that allows attackers with write access to a shared artifact store to execute arbitrary code by planting a malicious pickle file. Attackers can replace a stored artifact.pkl file with a crafted cloudpickle payload containing a malicious reduce method, which executes arbitrary system commands when any user or pipeline materializes the artifact through the unsanitized cloudpickle.load() call in cloudpickle_materializer.py.
