    CVE-2026-56121 (GCVE-0-2026-56121)

    Vulnerability from cvelistv5 – Published: 2026-06-24 14:49 – Updated: 2026-06-24 16:03 X_Open Source

    Title
    Feast < 0.63.0 Unauthenticated RCE via ApplyFeatureView gRPC Deserialization
    Summary
    Feast before 0.63.0 contains an unsafe deserialization vulnerability that allows unauthenticated or unauthorized attackers to achieve remote code execution by sending a crafted gRPC request to the registry server. The user_defined_function.body field of an OnDemandFeatureView spec is decoded from base64 and passed to dill.loads() before any authorization check is performed, enabling attackers to embed a malicious serialized Python object with an arbitrary __reduce__ method to execute OS commands as the feast service account.
