This repository has undergone a security audit. Critical vulnerabilities have been addressed, but there are still recommended improvements before deploying to production.

✅ SSRF Vulnerability (CRITICAL) - Fixed in app/api/download/route.ts

• Added URL allowlist validation
• Implemented HTTPS-only enforcement
• Added private IP range blocking
• Implemented file size limits and timeouts

✅ XSS Vulnerability (HIGH) - Fixed in components/organisms/standard-page-header.tsx

• Removed dangerouslySetInnerHTML usage
• Sanitized all user input rendering

✅ Information Disclosure (MEDIUM) - Fixed in multiple files

• Removed sensitive console.log statements
• Cleaned up PII logging in registration forms

✅ Security Headers (MEDIUM) - Added in next.config.mjs

• X-Frame-Options: DENY
• X-Content-Type-Options: nosniff
• X-XSS-Protection: 1; mode=block
• Referrer-Policy: strict-origin-when-cross-origin
• Permissions-Policy configured

Status: ⚠️ Not Implemented

All API routes are currently unauthenticated:

• /api/generate-upload-ursl
• /api/generate-cs-personal-submision-upload-urls
• /api/download

Recommendation:

// Example middleware for authentication
export async function middleware(request: NextRequest) {
  // Implement session validation
  // Add rate limiting
  // Verify user permissions
}

Status: ⚠️ Unknown (Verify in Supabase Dashboard)

Tables requiring RLS policies:

• registrations
• spiritual_seva_submission
• community_seva_records
• personal_seva_submission

Recommendation:

• Enable RLS on all tables in Supabase
• Create policies to restrict read/write access
• Test policies thoroughly before production

Status: ⚠️ Not Implemented

Recommendation:

// Using Vercel Rate Limiting or similar
import { Ratelimit } from "@upstash/ratelimit"

const ratelimit = new Ratelimit({
  redis: redis,
  limiter: Ratelimit.slidingWindow(10, "10 s"),
})

Status: ⚠️ Partially Implemented

Current issues:

• Client-controlled content-type
• No server-side file validation
• No malware scanning

Recommendation:

• Validate file magic bytes server-side
• Implement file type allowlist
• Add virus scanning (e.g., ClamAV)
• Randomize uploaded filenames
• Set strict file size limits

Status: ⚠️ Not Implemented

Recommendation:

// Add CSRF tokens to all forms
// Verify tokens in API routes
// Use SameSite cookie attributes

Status: ⚠️ Client-side Only

Current validation uses Zod schemas client-side only.

Recommendation:

• Duplicate all Zod validations in API routes
• Never trust client-side validation
• Sanitize all inputs before database insertion

Status: ⚠️ Not Implemented

Recommendation: Add CSP header to next.config.mjs:

{
  key: 'Content-Security-Policy',
  value: "default-src 'self'; script-src 'self' 'unsafe-eval' 'unsafe-inline'; ..."
}

Note: Requires careful configuration due to external resources (Cloudflare CDN, Supabase, etc.)

Status: ✅ Properly Configured

Good practices in place:

• .env files in .gitignore
• .env.local used for local secrets (gitignored)
• No hardcoded secrets found

Recommendation:

• Rotate R2 credentials regularly
• Use different credentials for dev/staging/prod
• Consider using secret management service

Status: ⚠️ Unknown

Recommendation:

# Regularly check for vulnerabilities
npm audit

# Update dependencies
npm update

# Fix vulnerabilities
npm audit fix

Status: ⚠️ Warnings Ignored

Current settings ignore TypeScript and ESLint errors:

eslint: { ignoreDuringBuilds: true },
typescript: { ignoreBuildErrors: true },

Recommendation:

• Fix all TypeScript errors
• Enable linting
• Address all warnings

Status: ✅ Protected by Supabase SDK

All database queries use Supabase SDK with parameterized queries, which prevents SQL injection.

Important: Never use raw SQL queries or concatenate user input into queries.

Status: ⚠️ Needs Attention

The application collects Personally Identifiable Information (PII):

• Names, email addresses, phone numbers
• Location data (country, mandal)
• Religious activity information

Recommendations:

1. Add Privacy Policy page
2. Implement GDPR compliance measures
3. Add user data deletion capability
4. Implement data retention policies
5. Add cookie consent banner if using cookies
6. Encrypt sensitive data at rest

Before going to production, perform:

1. Penetration Testing

   • Test all API endpoints
   • Attempt SQL injection, XSS, CSRF
   • Test file upload security
   • Verify authentication bypasses

2. Dependency Audit

   npm audit

3. Static Analysis

   npm run lint
   # Consider adding: ESLint security plugins

4. Manual Code Review

   • Review all API routes
   • Check for hardcoded secrets
   • Verify input validation
   • Review error handling

• Date: 2026-01-26
• Audited By: Automated security scan
• Critical Issues Found: 2 (Fixed)
• High Severity Issues: 5 (2 Fixed, 3 Recommendations)
• Medium Severity Issues: 4 (2 Fixed, 2 Recommendations)

Note: This is a portfolio project. While security improvements have been made, it should not be deployed to production without implementing all recommended security measures above.
