CriticalCVSS 9.3
Published: Translated: NVD NIST

Summary

Path Traversal and Missing Authorization in the cloud-storage source of Google Cloud MCP Toolbox for Databases (googleapis/mcp-toolbox) versions 1.2.0 through 1.4.0 allows an unauthenticated remote attacker to exfiltrate host files to external Google Cloud Storage buckets and overwrite arbitrary local files via crafted tool invocation parameters.

Risk Assessment

An unauthenticated attacker can steal sensitive host files and overwrite local files, leading to data leakage and potential integrity loss. The risk affects environments running vulnerable toolbox versions.

Recommendation

Upgrade Google Cloud MCP Toolbox for Databases to a version later than 1.4.0. Until patched, restrict network access to the tool and review service account permissions.
