OpenCost before 1.121.0 fails to authenticate the GET /helmValues endpoint, exposing base64-decoded HELM VALUES environment variable containing cloud provider credentials. Additionally, adminAuthMiddleware fails open when ADMIN TOKEN is unset, allowing unauthenticated attackers to modify GCP service account keys via POST /serviceKey to redirect billing calls.
