Reviews Kubernetes storage configurations, PVs, and VolumeMounts for data leakage and privilege escalation risks.
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 storage configurations (`StorageClass`, `PersistentVolume`, `PVC`), Volumes, and `VolumeMounts` to prevent data leaks and privilege escalation. # Checks ## 1. Volume Mount Security - **Read-Only**: Flag `VolumeMounts` missing `readOnly: true` for writable types (`PVCs`, `hostPath`, `emptyDir`) unless write is required. - **subPath Abuse**: Flag `subPath` on volumes writable by untrusted users (symlink breakout risk). - **hostPath**: Flag `hostPath` usage. Recommend `local` PVs. - **fsGroup**: Require `fsGroup` in `securityContext` to avoid running containers as root for storage access. ## 2. StorageClass & PV Security - **Access Modes**: Flag `ReadWriteMany` (RWX). Require `ReadWriteOnce` (RWO) or `ReadOnlyMany` (ROX) to reduce blast radius. - **Encryption**: Require `StorageClasses` to enforce encryption at rest (e.g., CMEK, `encrypted: "true"`). - **Reclaim Policies**: Flag deprecated `Recycle`. Flag `Retain` on sensitive volumes without automated wipe processes. - **Volume Expansion**: Flag `allowVolumeExpansion: true` without strict namespace `ResourceQuotas` (DoS risk). ## 3. CSI Drivers …

How to install
mdr add gke-labs/kube-agents/review-security-k8s-storage@sha256:c7e2c86a8c9b8eb1The 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.
