🔧 Remediation Steps (English)
Immediate Actions:
1. Audit all user role assignments in affected systems to identify unauthorized changes
2. Review access logs for updateUserRole function calls and suspicious role modifications
3. Implement input validation and sanitization for userId and role parameters
4. Add server-side authorization checks before processing role updates

Patching Guidance:
1. Upgrade next-saas-stripe-starter to version 1.0.1 or later when available
2. If upgrade not possible, implement compensating controls immediately

Compensating Controls:
1. Implement role-based access control (RBAC) validation on backend before any role modification
2. Add multi-factor authentication for administrative role changes
3. Implement request signing/verification to prevent parameter tampering
4. Use allowlists for valid role values

Detection Rules:
1. Monitor for POST/PUT requests to updateUserRole endpoint with suspicious userId patterns
2. Alert on role modifications that elevate user privileges
3. Track failed authorization attempts on role update functions
4. Monitor for rapid sequential role change requests from single source
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تدقيق جميع تعيينات أدوار المستخدمين في الأنظمة المتأثرة لتحديد التغييرات غير المصرح بها
2. مراجعة سجلات الوصول لاستدعاءات وظيفة updateUserRole والتعديلات المريبة على الأدوار
3. تنفيذ التحقق من صحة المدخلات والتطهير لمعاملات userId و role
4. إضافة فحوصات التفويض من جانب الخادم قبل معالجة تحديثات الأدوار

إرشادات التصحيح:
1. ترقية next-saas-stripe-starter إلى الإصدار 1.0.1 أو أحدث عند توفره
2. إذا لم يكن الترقية ممكنة، قم بتنفيذ الضوابط البديلة فوراً

الضوابط البديلة:
1. تنفيذ التحقق من التحكم في الوصول القائم على الأدوار (RBAC) على الخادم قبل أي تعديل دور
2. إضافة المصادقة متعددة العوامل لتغييرات الأدوار الإدارية
3. تنفيذ التوقيع على الطلب والتحقق منه لمنع تعديل المعاملات
4. استخدام قوائم السماح للقيم الدور الصحيحة

قواعد الكشف:
1. مراقبة طلبات POST/PUT إلى نقطة نهاية updateUserRole مع أنماط userId المريبة
2. التنبيه على تعديلات الأدوار التي ترفع امتيازات المستخدم
3. تتبع محاولات التفويض الفاشلة على وظائف تحديث الأدوار
4. مراقبة طلبات تغيير الأدوار المتسلسلة السريعة من مصدر واحد
