Task 10: Harden file upload validation
Enhanced validateFileUpload() function in functions.php with comprehensive security:
- Hardcoded MIME type whitelist per file type (profile_picture, proof_of_payment, document)
- Strict file size limits per type (5MB images, 10MB documents)
- Extension validation against whitelist
- Double extension prevention (e.g., shell.php.jpg)
- MIME type verification using finfo
- Image validation with getimagesize()
- is_uploaded_file() verification
- Random filename generation to prevent path traversal
Updated file upload handlers:
- upload_profile_picture.php - Profile picture uploads (JPEG, PNG, GIF, WEBP, 5MB max)
- submit_pop.php - Proof of payment uploads (PDF only, 10MB max) + CSRF validation + audit logging
- add_campsite.php - Campsite thumbnail uploads + input validation + CSRF validation + audit logging
Security improvements:
- All uploads use random filenames to prevent directory traversal
- All uploads use secure file permissions (0644)
- File validation occurs before move_uploaded_file()
- Comprehensive error logging for failed uploads
- Audit logging for successful file operations

Phase 1: Implement CSRF protection, input validation, and rate limiting
Major security improvements:
- Added CSRF token generation, validation, and cleanup functions
- Implemented comprehensive input validators (email, phone, name, date, amount, ID, file uploads)
- Added rate limiting with login attempt tracking and account lockout (5 failures = 15 min lockout)
- Implemented session fixation protection with session_regenerate_id() and 30-min timeout
- Fixed SQL injection in getResultFromTable() with whitelisted columns/tables
- Added audit logging for security events
- Applied CSRF validation to all 7 process_*.php files
- Applied input validation to critical endpoints (login, registration, bookings, application)
- Created database migration for login_attempts, audit_log tables and locked_until column
Modified files:
- functions.php: +500 lines of security functions
- validate_login.php: Added CSRF, rate limiting, session hardening
- register_user.php: Added CSRF, input validation, registration rate limiting
- process_*.php (7 files): Added CSRF token validation
- Created migration: 001_phase1_security_schema.sql
Next steps: Add CSRF tokens to form templates, harden file uploads, create testing checklist
