Fix security vulnerabilities in the project. * **SQL Injection**: Use parameterized queries in `model/auth.js` and `model/products.js` to prevent SQL injection. * **Hardcoded Secret**: Replace the hardcoded secret in `app.js` with an environment variable. * **Session Cookie**: Mark the session cookie as secure in `app.js`. * **CSRF Protection**: Implement CSRF protection using the `csurf` middleware in `app.js`. * **Open Redirect**: Validate the return URL in `routes/login.js` to prevent open redirect vulnerability. * **Log Injection**: Sanitize user input before logging in `routes/login.js` to prevent log injection. --- For more details, open the [Copilot Workspace session](https://copilot-workspace.githubnext.com/octodemo/vulnerable-node?shareId=XXXX-XXXX-XXXX-XXXX).
