CVE-2026-56121-Feast-Unauth-RCE

CVE-2026-56121 — Feast Unauthenticated RCE via gRPC Registry Deserialization The Feast 0.63.0 registry gRPC server dill.loads the user-defined function of an OnDemandFeatureView as soon as a spec arrives — before any authorization check. The shipped config is auth: noauth, so any client that can...

CVE-2026-56121_exploit

CVE-2026-56121 — Feast Registry Unauthenticated RCE dill.loads Unauthenticated remote code execution in the Feast feature store's registry gRPC server. The ApplyFeatureView RPC rebuilds an OnDemandFeatureView from the request proto. Doing so base64-decodes spec.userdefinedfunction.body and passes...
