CVE-2026-18948

A flaw was found in Feast. The system improperly deserializes user-defined functions UDFs stored in its registry, which are serialized using the 'dill' library. This allows a remote attacker to store a malicious UDF, leading to unauthenticated arbitrary code execution on the feature server in...

CVE-2026-18941

A flaw was found in Feast and feast-operator. The default configuration for both the Feast SDK and the feast-operator is "noauth," meaning no security manager is installed. This default allows unauthenticated and unauthorized access to feature-server, registry-server, and offline-server endpoints...
