CVE-2026-18941 - Feast: feast-operator: feast: default authentication mode is no_auth — shared multi-tenant instances deployed without authentication
CVE ID :CVE-2026-18941
Published : Aug. 10, 2026, 8:44 p.m. | 43 minutes ago
Description :A flaw was found in Feast and feast-operator. 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.
Severity: 7.7 | HIGH
