Description

Kubernetes Secrets Store CSI Driver Vault Plugin prior to v0.0.6, Azure Plugin prior to v0.0.10, and GCP Plugin prior to v0.2.0 allow an attacker who can create specially-crafted SecretProviderClass objects to write to arbitrary file paths on the host filesystem, including /var/lib/kubelet/pods.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/hashicorp/vault-csi-provider, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update github.com/hashicorp/vault-csi-provider to 0.0.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-2v35-wj4r-rcmv is resolved across your whole dependency graph.

  3. Workarounds

    Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.
