ZenML vulnerabilities

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.

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.

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.
