feat: implement critical security fixes for SQL injection and authentication vulnerabilities
Security Enhancements:
- Fix SQL injection vulnerabilities by replacing whereRaw queries with parameterized queries
- Add LIKE pattern escaping to prevent SQL injection in search functionality
- Implement account lockout protection (5 failed attempts = 30 min lockout)
- Add comprehensive login attempt tracking and audit trail
- Enhance JWT tokens with issuer validation, IP tracking, and password change detection
- Add logout endpoint and session management
- Prevent user enumeration with generic error messages

Database Changes:
- Add login_attempts table for authentication tracking
- Add security columns to admin_users (password_changed_at, last_login_ip, two_factor_enabled)

New Security Features:
- Brute force protection with configurable lockout duration
- Automatic cleanup of old login attempts
- Enhanced authentication middleware with stricter validation
- Monitoring scripts for security health checks

All fixes are backward compatible and production-ready with rollback plans included.

# SQL Injection Fix Rollback Plan
## Overview
This document provides a rollback plan in case the SQL injection fixes cause issues in production.
## Changes Made
1. **Created**: `backend/src/utils/sqlSecurity.js` - Central security utilities
2. **Modified**: `backend/src/routes/adminDashboard.js` - Replaced whereRaw with parameterized queries
3. **Modified**: `backend/src/routes/adminPhotos.js` - Added LIKE pattern escaping
4. **Modified**: `backend/src/routes/adminEvents.js` - Added LIKE pattern escaping
## Quick Rollback Steps
### Step 1: Revert Code Changes
If issues occur, run these commands to revert:
```bash
# Navigate to backend directory
cd backend
# Revert specific files
git checkout HEAD -- src/routes/adminDashboard.js
git checkout HEAD -- src/routes/adminPhotos.js
git checkout HEAD -- src/routes/adminEvents.js
# Remove the new security utility file
rm src/utils/sqlSecurity.js
```
### Step 2: Restart Services
```bash
# If using Docker
docker-compose restart backend
# If using PM2
pm2 restart picpeak-backend
```
## Verification After Rollback
1. Check admin dashboard loads: `/admin/dashboard`
2. Test event search functionality
3. Test photo search functionality
4. Verify analytics charts display correctly
## Symptoms That May Require Rollback
1. **Dashboard Statistics Not Loading**
- Empty or NaN values in stats
- Analytics charts not rendering
2. **Search Features Broken**
- Event search returns no results
- Photo search returns errors
- Special characters in search causing issues
3. **Date Filtering Issues**
- Activity logs not showing correct date ranges
- Analytics showing incorrect time periods
## Safe Testing Before Production
1. **Test in Development First**:
```bash
cd backend
npm run dev
```
2. **Test Key Features**:
- Admin dashboard stats: `http://localhost:3001/api/admin/dashboard/stats`
- Analytics: `http://localhost:3001/api/admin/dashboard/analytics?days=7`
- Event search: `http://localhost:3001/api/admin/events?search=test`
- Photo search: `http://localhost:3001/api/admin/events/1/photos?search=test`
3. **Monitor Logs**:
```bash
# Docker logs
docker-compose logs -f backend
# PM2 logs
pm2 logs picpeak-backend
```
## Emergency Contacts
- Keep database backups before deploying
- Have monitoring alerts for 500 errors
- Document any custom SQL queries in use
## Post-Rollback Actions
If rollback is needed:
1. Document the specific issue encountered
2. Create test cases for the failure scenario
3. Fix the issue in development
4. Re-test thoroughly before re-deploying
