 ## In-Progress Tasks 🟡
 None currently. All major implementation tasks completed.
 ---
 ## Remaining Tasks ⏳
 ### 9. Add CSRF Tokens to Form Templates (0% - NEXT)
 **Scope**: ~40+ forms across application
 **Task**: Add hidden CSRF token field to every `<form method="POST">` tag:
 ```html
 <input type="hidden" name="csrf_token" value="<?php echo generateCSRFToken(); ?>">
 ```
 **Estimate**: 2-3 hours
 **Files to audit**: All .php files with form tags, especially:
 - login.php
 - register.php
 - membership_application.php
 - update_application.php
 - profile/account editing forms
 - All booking forms (trips, camps, courses)
 - admin forms (member management, payment processing)
 ### 10. Harden File Upload Validation (0%)
 **File**: `process_application.php` (or relevant file upload handler)
 **Changes needed**:
 - Implement `validateFileUpload()` function usage
 - Set whitelist: jpg, jpeg, png, pdf only
 - Size limit: 5MB
 - Random filename generation with extension preservation
 - Verify destination is outside webroot (already done?)
 - Test with various file types and oversized files
 **Estimate**: 2-3 hours
 ### 11. Create Security Testing Checklist (0%)
 **Deliverable**: Document with test cases:
 - [ ] CSRF token bypass attempts (invalid/expired tokens)
 - [ ] Brute force login (5 failures should lock account)
 - [ ] SQL injection attempts on search/filter endpoints
 - [ ] XSS attempts in input fields
 - [ ] File upload validation (invalid types, oversized files)
 - [ ] Session hijacking attempts
 - [ ] Rate limiting on registration endpoint
 - [ ] Password strength validation
 **Estimate**: 1-2 hours

 ## Security Improvements Summary
 ### Before Phase 1
 - ❌ No CSRF protection
 - ❌ Basic input validation only
 - ❌ No rate limiting on login
 - ❌ No session fixation protection
 - ❌ SQL injection vulnerability in getResultFromTable()
 - ❌ No audit logging
 - ❌ No account lockout mechanism
 ### After Phase 1 (Current)
 - ✅ CSRF tokens on all POST forms (in progress - forms need tokens)
 - ✅ Comprehensive input validation on all endpoints
 - ✅ Login rate limiting with auto-lockout after 5 failures
 - ✅ Session fixation prevented with regenerate_id()
 - ✅ SQL injection fixed with whitelisting
 - ✅ Full audit logging of security events
 - ✅ Account lockout mechanism with 15-minute cooldown
 - ✅ Password strength requirements
 - ✅ Account unlock admin capability
 ---
 ## Database Changes Required
 Run `migrations/001_phase1_security_schema.sql` to:
 1. Create `login_attempts` table
 2. Create `audit_log` table
 3. Add `locked_until` column to `users` table
 4. Add appropriate indexes
 ---
 ## Testing Verification
 **Critical Path Tests Needed**:
 1. Login with valid credentials → should succeed
 2. Login with invalid password 5 times → should lock account
 3. Try login while locked → should show lockout message with time remaining
 4. After 15 minutes, login again → should succeed (lockout expired)
 5. Registration with invalid email → should reject
 6. Registration with weak password → should reject
 7. POST request without CSRF token → should be rejected with 403
 8. POST request with invalid CSRF token → should be rejected
 9. Account unlock by admin → should allow login immediately
 ---
 ## Next Immediate Steps
 1. **Find all form templates** with `method="POST"` (estimate 40+ forms)
 2. **Add CSRF token field** to each form: `<input type="hidden" name="csrf_token" value="<?php echo generateCSRFToken(); ?>">`
 3. **Test CSRF protection** - verify forms without token are rejected
 4. **Implement file upload validation** in process_application.php
 5. **Create testing checklist** document
 6. **Run database migration** when deployed to production
 7. **User acceptance testing** on all critical workflows

 # Phase 1 Task 9: Add CSRF Tokens to Forms - Quick Start Guide
 ## What to Do
 Every `<form method="POST">` in the application needs a CSRF token hidden field.
 ## How to Add CSRF Token to a Form
 ### Simple One-Line Addition
 Add this ONE line before the closing `</form>` tag:
 ```html
 <input type="hidden" name="csrf_token" value="<?php echo generateCSRFToken(); ?>">
 ```
 ### Complete Form Example
 **Before (Vulnerable)**:
 ```html
 <form method="POST" action="process_booking.php">
    <input type="text" name="from_date" required>
    <input type="text" name="to_date" required>
    <button type="submit">Book Now</button>
 </form>
 ```
 **After (Secure)**:
 ```html
 <form method="POST" action="process_booking.php">
    <input type="hidden" name="csrf_token" value="<?php echo generateCSRFToken(); ?>">
    <input type="text" name="from_date" required>
    <input type="text" name="to_date" required>
    <button type="submit">Book Now</button>
 </form>
 ```
 ## Forms to Update (Estimated 40+)
 ### Priority 1: Authentication & Membership (5 forms)
 - [ ] login.php - Login form
 - [ ] register.php - Registration form
 - [ ] forgot_password.php - Password reset request
 - [ ] reset_password.php - Password reset form
 - [ ] change_password.php - Change password form
 ### Priority 2: Bookings (6 forms)
 - [ ] campsite_booking.php - Campsite booking form
 - [ ] trips.php - Trip booking form
 - [ ] course_details.php - Course booking form
 - [ ] membership_application.php - Membership application form
 - [ ] update_application.php - Update membership form
 - [ ] view_indemnity.php - Indemnity acceptance form
 ### Priority 3: Account Management (4 forms)
 - [ ] account_settings.php - Account settings form
 - [ ] update_user.php - User profile update form
 - [ ] member_info.php - Member info edit form
 - [ ] upload_profile_picture.php - Profile picture upload form
 ### Priority 4: Admin Pages (6+ forms)
 - [ ] admin_members.php - Admin member management forms
 - [ ] admin_bookings.php - Admin booking management
 - [ ] admin_payments.php - Admin payment forms
 - [ ] admin_course_bookings.php - Course management
 - [ ] admin_trip_bookings.php - Trip management
 - [ ] admin_camp_bookings.php - Campsite management
 ### Priority 5: Other Forms (10+ forms)
 - [ ] comment_box.php
 - [ ] contact.php
 - [ ] blog_details.php (if has comment form)
 - [ ] bar_tabs.php / fetch_bar_tabs.php
 - [ ] events.php
 - [ ] create_bar_tab.php
 - [ ] Any other POST forms
 ## Search Strategy
 ### Option 1: Use Grep to Find All Forms
 ```bash
 # Find all forms in the application
 grep -r "method=\"POST\"" --include="*.php" .
 # Or find AJAX forms that might not have method="POST"
 grep -r "<form" --include="*.php" . | grep -v method
 ```
 ### Option 2: Manual File-by-File Check
 Look for these patterns:
 - `<form method="POST"`
 - `<form` (default is POST if not specified)
 - `<form method='POST'`
 ## Common Patterns
 ### Standard Form
 ```html
 <form method="POST">
    <!-- fields -->
    <input type="hidden" name="csrf_token" value="<?php echo generateCSRFToken(); ?>">
    <button type="submit">Submit</button>
 </form>
 ```
 ### Form with Action
 ```html
 <form method="POST" action="process_booking.php">
    <!-- fields -->
    <input type="hidden" name="csrf_token" value="<?php echo generateCSRFToken(); ?>">
    <button type="submit">Submit</button>
 </form>
 ```
 ### AJAX Form (Special Case)
 For AJAX/JavaScript forms that serialize and POST:
 ```javascript
 // In your JavaScript, before sending:
 const formData = new FormData(form);
 formData.append('csrf_token', '<?php echo generateCSRFToken(); ?>');
 ```
 ### Admin/Modal Forms
 ```html
 <form method="POST" class="modal-form">
    <input type="hidden" name="csrf_token" value="<?php echo generateCSRFToken(); ?>">
    <!-- fields -->
 </form>
 ```
 ## Validation Reference
 After adding CSRF tokens, the server-side code already validates them:
 ### Login Endpoint
 ✅ `validate_login.php` - CSRF validation implemented
 ### Registration Endpoint
 ✅ `register_user.php` - CSRF validation implemented
 ### Booking Endpoints
 ✅ `process_booking.php` - CSRF validation implemented
 ✅ `process_camp_booking.php` - CSRF validation implemented
 ✅ `process_trip_booking.php` - CSRF validation implemented
 ✅ `process_course_booking.php` - CSRF validation implemented
 ✅ `process_signature.php` - CSRF validation implemented
 ✅ `process_application.php` - CSRF validation implemented
 ✅ `process_eft.php` - CSRF validation implemented
 **If you add CSRF to a form but the endpoint doesn't validate it yet**, the form will still work but the endpoint needs to be updated to include:
 ```php
 if (!isset($_POST['csrf_token']) || !validateCSRFToken($_POST['csrf_token'])) {
    // Handle CSRF error
    echo json_encode(['status' => 'error', 'message' => 'Security token validation failed.']);
    exit();
 }
 ```
 ## Testing After Adding Tokens
 1. **Normal submission**: Form should work as before
 2. **Missing token**: Form should be rejected (if endpoint validates)
 3. **Invalid token**: Form should be rejected (if endpoint validates)
 4. **Expired token** (after 1 hour): New token needed
 ## Performance Note
 `generateCSRFToken()` is called once per page load. It's safe to call multiple times on the same page - each form gets a unique token.
 ## Common Issues & Solutions
 ### Issue: "Token validation failed" error
 **Solution**: Ensure `csrf_token` is passed in the POST data. Check:
 1. Form includes `<input type="hidden" name="csrf_token" value="<?php echo generateCSRFToken(); ?>">`
 2. Form method is POST (not GET)
 3. JavaScript doesn't strip the field
 ### Issue: Forms in modals not working
 **Solution**: Ensure token is inside the modal's form tag, not outside
 ### Issue: Multi-page forms not working
 **Solution**: Each page needs its own token. Token changes with each page load. This is intentional (single-use tokens).
 ## Checklist for Task 9
 - [ ] Identify all forms with `method="POST"` or no method specified
 - [ ] Add `<input type="hidden" name="csrf_token" value="<?php echo generateCSRFToken(); ?>">` to each
 - [ ] Test 5 critical forms to verify they still work
 - [ ] Test that form submission without CSRF token fails (if endpoint validates)
 - [ ] Verify password reset, login, and booking flows work
 - [ ] Commit changes with message: "Add CSRF tokens to all form templates"
