📝 LLM Analysis
🔸 Vulnerability Description
The code is vulnerable due to the lack of rate limiting for an endpoint that performs an expensive file system operation. This can lead to Denial-of-Service (DoS) attacks if an attacker sends a large number of requests in a short period.
🔸 Recommended Fix
Implement a rate-limiting middleware using a package like express-rate-limit to limit the number of requests to the endpoint that serves the index.html file.
🔸 Additional Notes
Ensure that the express-rate-limit package is installed in your project by running npm install express-rate-limit. The rate limit is set to 100 requests per 15 minutes per IP address, which can be adjusted based on your application's needs.
🛠 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.
