Summary
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.
Risk Assessment
An attacker with access to the artifact store can execute arbitrary code on the server, potentially leading to full system compromise.
Recommendation
Upgrade ZenML to the latest version that fixes this vulnerability and restrict access to the artifact store.

ZenML versions 0.57.0 through 0.94.2 have a vulnerability that allows bypassing rate-limiting on login and password change endpoints by rotating the X-Forwarded-For header. The rate limiter keys requests by request.client.host, which is derived from this header.
- CVE-2026-11876Medium
Vulnerability in zenml-io/zenml version 0.94.2. The `GET /api/v1/stack-deployment/stack` endpoint lacks proper RBAC checks, allowing any authenticated user to enumerate all deployed stacks (including component details, service connector info, and owner IDs) across all tenants.
Original NVD description (English source)
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.
