NewCVE-2026-18947 (opens in a new tab)How to fix?
There is no fixed version for feast.
Overview
feast is a Python SDK for Feast
Affected versions of this package are vulnerable to Incorrect Behavior Order: Early Amplification in the /materialize and /materialize-incremental endpoints. An attacker can trigger a full re-materialization of all feature views, causing denial of service, by sending a specially crafted request that omits the feature_views field.
This bypasses the intended permission checks for those endpoints and can be exercised by an unauthenticated remote attacker or any authenticated user. The result is significant resource consumption and data corruption that disrupts service for all tenants.
