📝 LLM Analysis

🔸 Vulnerability Description

The Express application is exposing the "X-Powered-By" HTTP header, which reveals information about the server framework being used (Express). This can be exploited by attackers to tailor their attacks based on the known vulnerabilities of the framework.

🔸 Recommended Fix

Disable the "X-Powered-By" header by using the app.disable('x-powered-by') method or by using security middleware like Helmet.

🔸 Additional Notes

Disabling the "X-Powered-By" header is a simple yet effective way to reduce the exposure of server information. For enhanced security, consider using additional middleware like Helmet to set various HTTP headers for security purposes.

🛠 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.
