Fix underscore vulnerability SNYK-JS-UNDERSCORE-1080984

Summary

This PR fixes a medium severity arbitrary code injection vulnerability in the underscore package (CVE-2021-23358) by upgrading the cfenv dependency from ^1.0.4 to ^1.2.4. The vulnerable underscore@1.9.1 was a transitive dependency introduced through cfenv@1.2.2, and the upgrade pulls in underscore@1.12.1 which contains the security fix.

Key Changes:

• Updated cfenv version in package.json from ^1.0.4 to ^1.2.4
• This automatically upgrades underscore from 1.9.1 to 1.12.1 via the dependency tree
• The vulnerability allowed arbitrary code injection through the underscore template function when the variable option was unsanitized

Review & Testing Checklist for Human

• Start the application locally and verify it runs without errors - I couldn't fully test this due to missing MongoDB setup
• Confirm the underscore vulnerability is resolved - Run npm audit and verify SNYK-JS-UNDERSCORE-1080984 is no longer reported
• Test core application functionality - Verify todo list creation, file upload, and other key features still work as expected since this is a demo app
• Check for new compatibility issues - Ensure the cfenv upgrade (1.0.4 → 1.2.4) doesn't break Cloud Foundry environment detection

Recommended Test Plan:

1. Set up MongoDB locally and start the application with npm start
2. Test basic todo operations (create, view, delete)
3. Test file upload functionality
4. Run npm audit to confirm vulnerability count decreased
5. Verify Cloud Foundry environment variables are still detected correctly if applicable

Notes

• Vulnerability Details: SNYK-JS-UNDERSCORE-1080984 (CVE-2021-23358) allowed arbitrary code injection via the underscore template function when variable option from _.templateSettings was not sanitized
• Fix Verification: After the upgrade, npm list underscore shows version 1.12.1 and npm audit no longer reports the underscore vulnerability
• Session Info: Requested by Shawn Azman (@ShawnAzman) - Link to Devin run

⚠️ Important: This is a deliberately vulnerable demo application. Please ensure that upgrading this dependency doesn't interfere with the app's intended educational/testing purpose for other security vulnerabilities.
