What is CVE-2026-18947?

An authorization bypass vulnerability exists within the Feast service, specifically in the /materialize and /materialize-incremental endpoints. Attackers can exploit this flaw by sending a carefully crafted request that omits the feature_views field, allowing them to bypass the intended permission checks. This poses a significant risk, enabling unauthorized users to forcibly trigger a full re-materialization of all feature views. The potential consequences include a Denial of Service (DoS) attack, which can lead to data corruption and excessive resource consumption across all affected tenants.
