📝 LLM Analysis

🔸 Vulnerability Description

The code uses the eval() function to parse user input from req.body.preTax, req.body.afterTax, and req.body.roth. This is a security vulnerability because eval() can execute arbitrary code, which can lead to code injection attacks if the input is user-controllable.

🔸 Recommended Fix

Replace the use of eval() with safer alternatives such as parseInt() or parseFloat() to convert the input strings to numbers. This avoids executing the input as code.

🔸 Additional Notes

The use of parseFloat() is appropriate here as it safely converts strings to numbers without executing them as code. Ensure that any other parts of the application that handle user input are similarly scrutinized for potential security vulnerabilities.

72	Open Redirect	⚠️ WARNING	CWE-601	🔗

📝 LLM Analysis

🔸 Vulnerability Description

The code contains an Open Redirect vulnerability. It allows redirection to a URL specified by user input without validation, which can lead to users being redirected to malicious sites.

🔸 Recommended Fix

Implement an allow-list of trusted URLs and validate the user-supplied URL against this list before performing the redirection.

🔸 Additional Notes

It's important to maintain and update the allow-list of URLs as needed to ensure that only trusted destinations are included. This approach helps mitigate the risk of open redirects by ensuring that only pre-approved URLs can be used for redirection.

📝 LLM Analysis

🔸 Vulnerability Description

The session middleware settings are insufficiently protected. The session configuration lacks critical attributes like domain, expires, httpOnly, path, secure, and uses the default session cookie name, which can expose the application to various attacks.

🔸 Recommended Fix

Set the domain, expires, httpOnly, path, and secure attributes in the session cookie configuration. Use a custom session cookie name instead of the default.

🔸 Additional Notes

Ensure that the domain specified in the session cookie configuration matches your actual domain. Additionally, to use the secure attribute, the application must be served over HTTPS. Adjust the expires value according to your session management requirements.

🛠 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.
