Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

SQLBot 是一个基于大语言模型和 RAG（检索增强生成）的智能 Text-to-SQL 系统。在 1.9.0 版本之前，后端文件 中的 端点将客户端可控的 值直接拼接到生成的 SQL 语句中，且未对标识符进行安全处理。经过身份验证的用户可以配置 SQLBot 内部 PostgreSQL 服务的数据源，并构造一个特殊的 ，使其在只读策略下仍保持为 SELECT 操作，同时调用 、 或 函数。在默认的受信任回环认证配置下（经过测试验证），内部连接会接受无效的认证凭据，并以 PostgreSQL 超级用户权限执行查询

Vulnerability Title
SQLBot: Authenticated SQL Injection in previewData Resulting in Arbitrary File Read
Source: CVE Program / CVE List V5
Vulnerability Description
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.
