CyberRota Analysis

AI-Generated

OpenCost versions prior to 1.121.0 are vulnerable due to a lack of authentication on the GET /helmValues endpoint, which exposes sensitive cloud provider credentials in the HELM_VALUES environment variable. Furthermore, the adminAuthMiddleware allows unauthenticated access when the ADMIN_TOKEN is unset, enabling attackers to modify GCP service account keys through the POST /serviceKey endpoint, potentially redirecting billing calls. Organizations using OpenCost should prioritize patching this vulnerability to protect against unauthorized access and credential exposure.

Original NVD Description

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.
