📄 Description (English)

Crucial management API endpoints for cellular eSIM allocation do not validate caller authorization, allowing remote profiles to be rewritten or deleted.

🤖 AI Executive Summary

CVE-2026-49203 is a critical authorization bypass vulnerability in cellular eSIM management APIs that allows unauthorized remote profile manipulation. Attackers can rewrite or delete eSIM profiles without proper authentication, affecting mobile service delivery and subscriber management.

📄 Description (Arabic)

تفتقر نقاط نهاية واجهة برمجة تطبيقات إدارة eSIM الحرجة إلى التحقق من تفويض المتصل، مما يسمح بإعادة كتابة أو حذف الملفات الشخصية البعيدة بدون مصادقة. يمكن للمهاجمين الوصول إلى الملفات الشخصية للمشتركين وتعديلها أو حذفها، مما يؤدي إلى انقطاع الخدمة وسرقة الهوية.

🤖 ملخص تنفيذي (AI)

ثغرة تجاوز التفويض الحرجة في واجهات برمجة تطبيقات إدارة eSIM الخلوية تسمح بمعالجة الملفات الشخصية غير المصرح بها. يمكن للمهاجمين إعادة كتابة أو حذف ملفات eSIM دون المصادقة المناسبة، مما يؤثر على تسليم خدمات الهاتف المحمول.

🔧 Remediation Steps (English)
Immediately implement strict authorization validation on all eSIM management API endpoints using OAuth 2.0 or mutual TLS authentication. Enforce role-based access control (RBAC), conduct security code review of API implementations, apply principle of least privilege, implement API rate limiting, enable comprehensive audit logging, and deploy Web Application Firewall (WAF) rules to detect unauthorized API access patterns.
🔧 خطوات المعالجة (العربية)
تطبيق التحقق الصارم من التفويض على جميع نقاط نهاية واجهة برمجة تطبيقات إدارة eSIM باستخدام OAuth 2.0 أو مصادقة TLS المتبادلة. فرض التحكم في الوصول القائم على الأدوار، إجراء مراجعة أمان الكود، تطبيق مبدأ الامتيازات الأقل، تنفيذ تحديد معدل API، تفعيل تسجيل التدقيق الشامل، ونشر قواعد جدار الحماية لتطبيقات الويب.
