Reviews Kubernetes ServiceAccount configurations for identity management and least privilege boundaries.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Task Review Kubernetes ServiceAccount resources/configurations to ensure least privilege and strict identity boundaries. # Checks ## 1. Identity Boundaries & Defaults - **Default Usage**: Flag RBAC bindings assigned to the `default` service account. - **Identity Sprawl**: Flag custom ServiceAccounts shared across distinct applications. Enforce 1:1 app-to-account mapping. - **Token Automounting**: Require `automountServiceAccountToken: false` on ServiceAccounts. ## 2. Cloud IAM Bridges - **Workload Identity**: Flag ServiceAccounts shared across workloads mapped to a single cloud identity (e.g., GCP `iam.gke.io/gcp-service-account`). ## 3. Legacy & Over-provisioning - **Long-lived Tokens**: Flag explicit `Secret` objects of type `kubernetes.io/service-account-token`. Require ephemeral `TokenRequest` API. - **Image Pull Secrets**: Ensure `imagePullSecrets` don't grant broad access to corporate registries. - **Orphaned Identities**: Flag ServiceAccounts with RBAC bindings but no active workloads.

How to install
mdr add gke-labs/kube-agents/review-security-k8s-service-accounts@sha256:5247808fa1fc75caThe line at the top of this page pins the label git:20260521.2bcbdef, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
