Until a fix is available, restrict write access to the shared artifact store to trusted users only. Avoid materializing artifacts from untrusted or unverified sources. Monitor vendor channels for updates or official patches addressing this vulnerability.
Description
ZenML version 0.94.6 contains a remote code execution vulnerability in its CloudpickleMaterializer component. This flaw allows attackers with write access to a shared artifact store to execute arbitrary code by replacing a stored artifact.pkl file with a malicious cloudpickle payload. The vulnerability arises from the unsanitized use of cloudpickle.load(), which executes the malicious __reduce__ method embedded in the payload during artifact materialization.
