Feast Feature Server <=0.58.0 - Arbitrary File Read

Feast the open-source Feature Store Feature Server through 0.58.0 exposes an unauthenticated POST /read-document endpoint that reads an arbitrary, caller-supplied file path with no authentication and no path validation. The readdocumentendpoint handler passes the JSON filepath field straight to...

VulnCheck KEV: CVE-2026-23536

A security issue was discovered in the Feast Feature Server's /read-document endpoint that allows an unauthenticated remote attacker to read any file accessible to the server process. By sending a specially crafted HTTP POST request, an attacker can bypass intended access restrictions to...

CVE-2026-18948

A flaw was found in Feast. The system improperly deserializes user-defined functions UDFs stored in its registry, which are serialized using the 'dill' library. This allows a remote attacker to store a malicious UDF, leading to unauthenticated arbitrary code execution on the feature server in...

CVE-2026-18941

A flaw was found in Feast and feast-operator. The default configuration for both the Feast SDK and the feast-operator is "noauth," meaning no security manager is installed. This default allows unauthenticated and unauthorized access to feature-server, registry-server, and offline-server endpoints...

CVE-2026-18948 Feast: feast: unsafe dill deserialization of registry-stored udfs — rce on feature server and registry server

A flaw was found in Feast. The system improperly deserializes user-defined functions UDFs stored in its registry, which are serialized using the 'dill' library. This allows a remote attacker to store a malicious UDF, leading to unauthenticated arbitrary code execution on the feature server in...

CVE-2026-18948

Feast: A flaw in serializing UDFs with dill enabling unsafe deserialization leads to unauthenticated RCE on the feature server and, via deserialization bypass, on the registry server. A remote attacker can store a malicious UDF, with the risk of cross-tenant data access and lateral movement in de...
