CVE-2026-15829Network attack vector

Authenticated data disclosure via forecast parameter injection

Published Jul 21, 2026 · Updated Jul 21, 2026

SQL injection in Google MCP Toolbox for Databases 0.13.0 through 1.3.0 allows remote authenticated users to read arbitrary BigQuery tables. The bigquery-forecast tool inserts data_col, timestamp_col, and id_cols into an AI.FORECAST statement without escaping, then executes the assembled query without validating every referenced dataset. Any authenticated MCP user able to call the tool can escape a string field, cross the configured allowedDatasets boundary, and read tables available to the Toolbox service account.
