AI-suggested
Red Hat advisories related to OpenShift AI mention this CVE but do not provide a fix at this time. Until then, consider configuring authentication explicitly rather than relying on the default "no_auth" setting to reduce exposure.
Description
A security flaw was identified in Feast and feast-operator where the default configuration uses "no_auth," allowing unauthenticated and unauthorized access to key Feast service endpoints. This vulnerability enables remote attackers to execute arbitrary code by uploading malicious user-defined functions, cause denial of service by forcing re-materialization of tenant features, and access data across tenants without authorization. The vulnerability is tracked as CVE-2026-18941 with a high severity score of 7.7. Red Hat has acknowledged this issue in their advisories related to Red Hat OpenShift AI but has not yet provided a fix.
