CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:L/A:L
Summary
A flaw was found in the Feast operator. A malicious tenant could inject arbitrary code into their feature repository. This code would be executed by an automated process with elevated privileges, allowing the tenant to steal sensitive credentials. This could lead to a direct escalation of privileges, granting the tenant administrative control over the Kubernetes cluster.

Weaknesses
Workarounds
Configure the Feast operator to use a dedicated, minimally-privileged ServiceAccount for the feast apply CronJob, ensuring automountServiceAccountToken: false is set. Apply a restricted securityContext to the CronJob pod and implement network policies to limit egress to only required registry endpoints. Ensure the CronJob ServiceAccount is separate from the feature-server ServiceAccount.
