🔒 Update dependencies to fix security vulnerabilities

[0GiS0]

🔍 Issue

The project currently has 16 npm security vulnerabilities (4 low, 1 moderate, 9 high, 2 critical) in its dependencies:

• body-parser - High severity: vulnerable to denial of service when url encoding is enabled
• ejs - Moderate severity: lacks certain pollution protection
• express - High severity: XSS vulnerability via response.redirect() and open redirect in malformed URLs
• braces - High severity: uncontrolled resource consumption
• cookie - Low severity: accepts cookie name, path, and domain with out of bounds characters
• brace-expansion - Low severity: Regular Expression Denial of Service vulnerability

💡 Proposed Solution

Run npm audit fix to automatically update dependencies to patched versions. Most vulnerabilities can be resolved by updating to:

• body-parser: 1.20.1 → 1.20.4
• ejs: 3.1.8 → 3.1.10
• express: 4.18.2 → 4.22.1
• dotenv: 16.0.3 → 16.6.1
• node-fetch: 3.3.0 → 3.3.2
• nodemon: 2.0.20 → 2.0.22

🎯 Benefits

• Eliminates known security vulnerabilities
• Protects against DoS, XSS, and injection attacks
• Ensures the demo application follows security best practices
• Makes the codebase safer for others to learn from and fork
