+# WordPress Rollbar Plugin - CSRF Security Fixes
+
+## Overview
+This document outlines the comprehensive CSRF (Cross-Site Request Forgery) security fixes implemented in the WordPress Rollbar Plugin to address the vulnerability identified in version <= 2.7.1.
+
+## Vulnerabilities Fixed
+
+### 1. Admin Post Action Handler (restoreDefaultsAction)
+**File:** `src/Settings.php`
+**Issue:** No nonce verification or capability checks
+**Fix:**
+- Added `wp_verify_nonce()` verification
+- Added `current_user_can('manage_options')` capability check
+- Added admin context verification
+
+### 2. REST API Endpoint (/test-php-logging)
+**File:** `src/Plugin.php`
+**Issue:** `permission_callback` was `__return_true` (allowed anyone)
+**Fix:**
+- Changed permission callback to require logged-in users with `manage_options` capability
+- Added nonce verification
+- Added input sanitization callbacks
+- Added admin context verification
+
+### 3. Main Settings Form
+**File:** `src/Settings.php`
+**Issue:** Missing nonce field
+**Fix:**
+- Added `wp_nonce_field()` for CSRF protection
+- Added nonce verification hook
+- Added capability checks
+
+### 4. Test Button Functionality
+**File:** `public/js/RollbarWordpressSettings.js`
+**Issue:** No CSRF protection in AJAX requests
+**Fix:**
+- Added nonce to localized script data
+- Modified JavaScript to include nonce in test requests
+
+### 5. Admin Menu Access
+**File:** `src/Settings.php`
+**Issue:** No verification for admin menu link access
+**Fix:**
+- Added nonce to admin menu links
+- Added nonce verification for menu access
+
+## Security Improvements Implemented
+
+### Nonce Verification
+- All form submissions now include nonce fields
+- All AJAX requests include nonce verification
+- Admin actions verify nonce before execution
+
+### Capability Checks
+- All admin functions require `manage_options` capability
+- User permissions verified before any sensitive operations
+- Proper WordPress role-based access control
+
+### Input Sanitization
+- REST API parameters sanitized using WordPress functions
+- `sanitize_text_field()` for text inputs
+- `absint()` for numeric inputs
+
+### Context Verification
+- Admin context verification for all admin functions
+- Session validation for flash messages
+- Proper request origin validation
+
+### Session Security
+- Flash message system protected against unauthorized access
+- Session manipulation prevention
+- Proper cleanup of session data
+
+## Files Modified
+
+1. **src/Settings.php**
+ - Added nonce fields to forms
+ - Added capability checks
+ - Added nonce verification hooks
+ - Enhanced security for all admin functions
+
+2. **src/UI.php**
+ - Added nonce field to restore defaults form
+ - Fixed "WordPress" capitalization
+
+3. **src/Plugin.php**
+ - Fixed REST API permission callback
+ - Added nonce verification to test endpoint
+ - Added input sanitization
+ - Fixed "WordPress" capitalization
+
+4. **public/js/RollbarWordpressSettings.js**
+ - Added nonce to AJAX requests
+ - Fixed "WordPress" capitalization
+
+## Testing Recommendations
+
+1. **Nonce Verification**
+ - Test form submissions with invalid/missing nonces
+ - Verify nonce expiration handling
+
+2. **Capability Checks**
+ - Test with users having different permission levels
+ - Verify unauthorized access is properly blocked
+
+3. **REST API Security**
+ - Test endpoint access without authentication
+ - Verify nonce requirements
+ - Test with invalid input parameters
+
+4. **Form Security**
+ - Test all forms with proper and improper nonces
+ - Verify CSRF protection works as expected
+
+## WordPress Standards Compliance
+
+All fixes follow WordPress coding standards and security best practices:
+- Uses WordPress nonce system (`wp_nonce_field`, `wp_verify_nonce`)
+- Implements proper capability checks (`current_user_can`)
+- Follows WordPress input sanitization patterns
+- Maintains backward compatibility
+- Uses WordPress admin context verification
+
+## Impact
+
+These security improvements significantly enhance the plugin's security posture by:
+- Preventing CSRF attacks on all admin functions
+- Ensuring only authorized users can perform sensitive operations
+- Protecting against unauthorized API access
+- Implementing defense-in-depth security measures
+- Following WordPress security best practices
+
+## Version Compatibility
+
+These fixes are compatible with:
+- WordPress 5.0+
+- PHP 7.4+
+- All modern browsers supporting JavaScript
+
+## Notes
+
+- The fixes maintain backward compatibility
+- No breaking changes to existing functionality
+- Enhanced security without performance impact
+- Follows WordPress security guidelines
+- Implements industry-standard CSRF protection
