📄 Description (English)
The Royal Elementor Addons plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'status' parameter in the wpr_update_form_action_meta AJAX action in all versions up to, and including, 1.7.1056. This is due to insufficient input sanitization and output escaping, combined with a publicly leaked nonce that allows unauthenticated access to the AJAX handler. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all WordPress installations using Royal Elementor Addons plugin version 1.7.1056 or earlier
2. Disable the plugin immediately if no patch is available
3. Audit website logs for suspicious AJAX requests to 'wpr_update_form_action_meta' endpoint
4. Search database for stored XSS payloads in form metadata
PATCHING GUIDANCE:
1. Monitor Royal Elementor Addons official repository for security updates
2. When patch becomes available, update to version 1.7.1057 or later immediately
3. Test updates in staging environment before production deployment
COMPENSATING CONTROLS (if patch unavailable):
1. Implement Web Application Firewall (WAF) rules to block requests to 'wpr_update_form_action_meta' AJAX action
2. Apply input validation at WAF level to reject requests with suspicious characters in 'status' parameter
3. Implement Content Security Policy (CSP) headers to prevent inline script execution
4. Disable AJAX functionality for unauthenticated users via WordPress security plugins
5. Implement rate limiting on AJAX endpoints
DETECTION RULES:
1. Monitor for POST requests to '/wp-admin/admin-ajax.php?action=wpr_update_form_action_meta'
2. Alert on 'status' parameter containing: <script>, javascript:, onerror=, onload=, event handlers
3. Monitor database for sudden changes to form metadata containing script tags
4. Track user sessions accessing pages with injected content
5. Log all AJAX requests from unauthenticated users
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع تثبيتات WordPress التي تستخدم إضافة Royal Elementor Addons الإصدار 1.7.1056 أو أقدم
2. تعطيل الإضافة فوراً إذا لم يكن هناك تصحيح متاح
3. تدقيق سجلات الموقع للطلبات المريبة إلى نقطة نهاية AJAX
4. البحث في قاعدة البيانات عن حمولات XSS المخزنة في بيانات النموذج
إرشادات التصحيح:
1. مراقبة مستودع Royal Elementor Addons الرسمي للتحديثات الأمنية
2. عند توفر التصحيح، قم بالتحديث إلى الإصدار 1.7.1057 أو أحدث فوراً
3. اختبر التحديثات في بيئة التدريج قبل نشرها في الإنتاج
الضوابط البديلة (إذا لم يكن التصحيح متاحاً):
1. تطبيق قواعد جدار حماية تطبيقات الويب لحظر الطلبات إلى إجراء AJAX
2. تطبيق التحقق من صحة المدخلات على مستوى WAF لرفض الطلبات ذات الأحرف المريبة
3. تطبيق رؤوس سياسة أمان المحتوى لمنع تنفيذ النصوص البرمجية المضمنة
4. تعطيل وظيفة AJAX للمستخدمين غير المصرح لهم
5. تطبيق تحديد معدل على نقاط نهاية AJAX
قواعد الكشف:
1. مراقبة طلبات POST إلى نقطة نهاية AJAX
2. التنبيه على معامل 'status' يحتوي على: <script>، javascript:، onerror=، onload=
3. مراقبة قاعدة البيانات للتغييرات المفاجئة في بيانات النموذج
4. تتبع جلسات المستخدم التي تصل إلى الصفحات المحقونة
5. تسجيل جميع طلبات AJAX من المستخدمين غير المصرح لهم
