NewCVE-2026-18941 (opens in a new tab)How to fix?
There is no fixed version for feast.
Overview
feast is a Python SDK for Feast
Affected versions of this package are vulnerable to Missing Authentication for Critical Function through the feature-server, registry-server, and offline-server endpoints when the default no_auth configuration leaves no security manager installed. An attacker can gain unauthorized access, execute arbitrary code, and trigger denial of service by sending requests to these exposed endpoints, including storing a malicious User-Defined Function on the feature-server or forcing re-materialization of all tenant features. This exposes cross-tenant feature data and can disrupt service for affected users and tenants.
