Summary
A flaw was found in Feast. An authorization bypass vulnerability exists in the /materialize and /materialize-incremental endpoints.
By sending a specially crafted request that omits the feature_views field, an attacker can bypass intended permission checks. This allows an unauthenticated remote attacker, or any authenticated user, to trigger a full re-materialization of all feature views.
The consequence is a Denial of Service (DoS) due to data corruption and significant resource consumption across all tenants.
Affected product named by the advisory: Red Hat OpenShift AI (RHOAI).
