Title
SQLBot: Authenticated SQL Injection in previewData Resulting in Arbitrary File Read
Summary
SQLBot is an intelligent Text-to-SQL system based on large language models and RAG. Prior to 1.9.0, the POST /api/v1/datasource/previewData endpoint in backend/apps/datasource/crud/datasource.py incorporates the client-controlled table_name value into generated SQL without safe identifier handling. An authenticated user can configure a datasource for SQLBot's internal PostgreSQL service and submit a crafted table_name that remains a SELECT operation under the read-only policy while invoking pg_read_file(), pg_read_binary_file(), or pg_ls_dir(). In the default tested trusted loopback authentication configuration, the internal connection accepts invalid credentials and executes with PostgreSQL superuser privileges, allowing filesystem content such as /etc/hosts and /etc/passwd to be returned in the previewData API response and potentially exposing configuration, credentials, authentication secrets, and source code. This issue is fixed in version 1.9.0.
