📝 LLM Analysis

🔸 Vulnerability Description

The Express application exposes the "X-Powered-By" header, which reveals information about the underlying framework used, potentially aiding attackers in targeting specific vulnerabilities. Additionally, the application performs a file system operation without rate limiting, which could be exploited for Denial-of-Service (DoS) attacks.

🔸 Recommended Fix

Use the Helmet middleware to disable the "X-Powered-By" header and add a rate-limiting middleware to protect endpoints that perform expensive operations.

🔸 Additional Notes

The Helmet middleware is used to enhance security by setting various HTTP headers, including disabling the "X-Powered-By" header. The express-rate-limit middleware is applied globally to limit the number of requests from a single IP address, mitigating the risk of DoS attacks.

🛠 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.
