CVE-2026-53557: SQLBot second-order SQL injection through Excel datasource tableName

Summary

SQLBot, a Text-to-SQL system built on large language models and RAG, is affected prior to version 1.9.0. An authenticated user can submit a crafted sheet["tableName"] value through POST /api/v1/datasource/, which is stored without safe identifier handling. When the datasource is later removed via DELETE /api/v1/datasource/{id}, PostgreSQL executes the stored value in cleanup SQL, allowing COPY TO PROGRAM and arbitrary operating-system commands under the postgres process privileges inside the SQLBot container.

Mitigation

Fixed in version 1.9.0.
