Parameters from the server's own tool schema.
The tool exports (reads) investment follow-up records from an ERP system into an Excel file. It retrieves existing data without modifying or deleting anything. The medium severity reflects that it exports potentially sensitive business/investment data from an ERP system, which could expose confidential commercial information if misused.
From the tool's definition 导出招商跟进记录Excel文件 (export investment follow-up records as Excel file); 'export执行导出' — this is a data export/read operation retrieving records from ERP system
