  "details" : [ "A high-severity remote code execution vulnerability exists in feast-dev/feast version 0.53.0, specifically in the Kubernetes materializer job located at `feast/sdk/python/feast/infra/compute_engines/kubernetes/main.py`. The vulnerability arises from the use of `yaml.load(..., Loader=yaml.Loader)` to deserialize `/var/feast/feature_store.yaml` and `/var/feast/materialization_config.yaml`. This method allows for the instantiation of arbitrary Python objects, enabling an attacker with the ability to modify these YAML files to execute OS commands on the worker pod. This vulnerability can be exploited before the configuration is validated, potentially leading to cluster takeover, data poisoning, and supply-chain sabotage.", "A flaw was found in Feast, specifically in the Kubernetes materializer job. An attacker with the ability to modify specific YAML configuration files can exploit an insecure deserialization vulnerability. This allows for the instantiation of arbitrary Python objects, leading to remote code execution on the worker pod. Successful exploitation could result in cluster takeover, data poisoning, and supply-chain sabotage." ],
  "statement" : "This vulnerability is rated Important for Red Hat OpenShift AI because an attacker with low privileges and local access to the worker pod can modify specific YAML configuration files. This insecure deserialization allows for remote code execution, potentially leading to cluster takeover, data poisoning, and supply-chain sabotage. This affects Red Hat OpenShift AI versions 2.22, 2.25, and 3.0.",
