What it is
SQLBot is an intelligent Text-to-SQL system based on large language models and RAG. Prior to 1.9.0, an authenticated user can supply a crafted sheet["tableName"] value in the Excel datasource configuration submitted through POST /api/v1/datasource/, and SQLBot stores that value without safe identifier handling. When the same datasource is later removed through DELETE /api/v1/datasource/{id}, the stored value is interpolated into datasource cleanup SQL and executed by PostgreSQL. This second-order SQL injection can invoke PostgreSQL COPY TO PROGRAM and execute arbitrary operating-system commands with the privileges of the postgres process inside the SQLBot container. This issue is fixed in version 1.9.0.
