Frequently Asked Questions

What is CVE-2026-18947?

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.

Is CVE-2026-18947 actively exploited?

No confirmed active exploitation of CVE-2026-18947 has been reported, but organizations should still patch proactively.

How to fix CVE-2026-18947?

No patch is currently available. Monitor vendor advisories for updates.

What is the CVSS score for CVE-2026-18947?

CVE-2026-18947 has a CVSS v3.1 base score of 8.5 (HIGH).
