📝 LLM Analysis

🔸 Vulnerability Description

The Express application exposes the X-Powered-By header, which reveals information about the framework being used. Additionally, unsanitized input from the HTTP request body is used directly in database queries, leading to potential SQL Injection vulnerabilities.

🔸 Recommended Fix

Use the Helmet middleware to disable the X-Powered-By header. Ensure that input data is properly sanitized or validated before being used in database queries.

🔸 Additional Notes

The use of Helmet middleware helps secure the application by setting various HTTP headers, including disabling the X-Powered-By header. Input validation and sanitization are crucial to prevent SQL Injection vulnerabilities. Always ensure that inputs are validated and sanitized before use in any database operations.

🛠 Fix Summary

All identified vulnerabilities have been remediated following security best practices such as parameterized queries and proper input validation. Please refer to the diff tab for detailed code changes.
