What is CVE-2026-18941?

A security flaw in the Feast SDK and feast-operator arises from a default configuration that lacks authentication, allowing unauthorized access to key server endpoints. This vulnerability enables attackers to potentially execute remote code via malicious User-Defined Functions (UDFs) and can lead to denial of service (DoS) by forcing unnecessary re-materialization of features across tenants. Moreover, it poses a risk of unauthorized access to cross-tenant data, which can drastically compromise data integrity and privacy.
