CVE-2026-23538 HIGH PATCH This Week

Denial of service in the Feast Feature Server (the Python feature-store serving component, also shipped within Red Hat OpenShift AI/RHOAI) lets remote unauthenticated attackers exhaust host resources through its `/ws/chat` WebSocket endpoint. Because the endpoint accepts unlimited concurrent connections and unbounded message traffic, opening many simultaneous sockets drains memory, CPU, and file descriptors until legitimate clients are locked out. There is no public exploit identified at time of analysis and this is not listed in CISA KEV; the upstream fix in PR #192 caps connections, message size, and message rate.

CVE-2026-23537 CRITICAL PATCH Act Now

Arbitrary file write in the Feast Feature Server's `/save-document` endpoint lets an unauthenticated remote attacker write attacker-controlled JSON to the host filesystem, bypassing the endpoint's path restrictions to overwrite application configuration or startup scripts. Because no credentials are required (CVSS 9.1, PR:N), any network-reachable attacker can corrupt system integrity, cause denial of service through disk exhaustion, or potentially achieve remote code execution. This flaw also ships in Red Hat OpenShift AI (RHOAI), which bundles Feast; there is no public exploit identified at time of analysis and it is not in CISA KEV.
