DescriptionCVE.org

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.

AnalysisAI

Authorization bypass in Feast's materialization API endpoints within Red Hat OpenShift AI (RHOAI) permits full re-materialization of all feature views by sending a crafted request that omits the feature_views field, circumventing permission checks. The consequence is a multi-tenant Denial of Service through data corruption and significant resource exhaustion, impacting all tenants sharing the deployment. …

Vulnerability AssessmentAI

Exploitation The /materialize or /materialize-incremental REST endpoints must be network-accessible to the attacker. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment Multiple signals converge on elevated real-world priority for RHOAI deployments. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker with network access to the RHOAI Feast API sends a POST request to the /materialize endpoint with a valid request body that deliberately omits the feature_views field. The authorization check fails to properly validate permissions without this field and proceeds, triggering a full re-materialization of every feature view across all tenants - consuming substantial compute, memory, and storage resources and potentially corrupting feature data in the online store. …
Remediation Consult the Red Hat security advisory at https://access.redhat.com/security/cve/CVE-2026-18947 for official patch guidance, as no specific patched RHOAI version is identified in the available data - patch version is not independently confirmed at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, identify all Red Hat OpenShift AI deployments with Feast materialization enabled and audit API access logs for suspicious requests lacking the feature_views field; document baseline API activity for anomaly detection. …
