📝 LLM Analysis

🔸 Vulnerability Description

The code sets the rejectUnauthorized option to false in the nodemailer.createTransport configuration. This bypasses TLS verification, which can make the application vulnerable to man-in-the-middle (MITM) attacks.

🔸 Recommended Fix

Enable TLS verification by setting rejectUnauthorized to true or removing the tls configuration entirely to use the default secure settings.

🔸 Additional Notes

The rejectUnauthorized: false option was removed to ensure that the default secure settings are used, which include verifying the server's certificate against a list of trusted CAs. This change helps in maintaining secure communication.

📝 LLM Analysis

🔸 Vulnerability Description

The cookie-session middleware is configured with default settings that lack important security attributes. Specifically, the domain, expires, httpOnly, path, and secure options are not set, which can lead to insufficiently protected credentials.

🔸 Recommended Fix

Set the domain, expires, httpOnly, path, and secure options in the cookie-session configuration to enhance security. Use secure and appropriate values for these options based on your application's requirements.

🔸 Additional Notes

• Replace 'example.com' with your actual domain.
  • Adjust the expires value as per your session management policy.
  • Ensure your application is served over HTTPS to use the secure flag effectively.

🛠 Fix Summary
