The default configuration for both the Feast SDK and the feast-operator is \"no_auth,\" meaning no security manager is installed. This default allows unauthenticated and unauthorized access to feature-server, registry-server, and offline-server endpoints. A remote attacker, by exploiting this missing authentication, could achieve remote code execution (RCE) by storing a malicious User-Defined Function (UDF) on the feature-server, trigger a denial of service (DoS) by forcing re-materialization of all tenant features, and gain unauthorized access to cross-tenant data.","state":0,"publishedAt":"2026-08-10T20:44:42.322+00:00","modifiedAt":"2026-10-19T11:10:07.013+00:00","affected":[{"ecosystem":"https://catalog.redhat.com/software/containers/","name":"rhoai/odh-feature-server-rhel9","ranges":[],"versions":[],"rawVersionEvidence":"{\n
