📄 Description (English)
CAI Content Credentials versions 0.78.2, 0.7.0 and earlier are affected by an Uncontrolled Resource Consumption vulnerability that could lead to application denial-of-service. An attacker could exploit this vulnerability to exhaust system resources, resulting in an application denial-of-service condition. Exploitation of this issue does not require user interaction.
🤖 AI Executive Summary
CVE-2026-34665 is a high-severity uncontrolled resource consumption vulnerability affecting Adobe's C2PA (Content Credentials) library versions 0.78.2 and earlier. The vulnerability allows unauthenticated attackers to trigger denial-of-service conditions by exhausting system resources without requiring user interaction. Currently, no patch is available, making immediate compensating controls critical for affected organizations.

🇸🇦 Saudi Arabia Impact Assessment
Saudi organizations in media, publishing, and digital content verification sectors are at elevated risk, particularly those using Adobe C2PA for content authentication and digital rights management. Government agencies (NCA, CITC) and financial institutions (SAMA-regulated banks) utilizing C2PA for document verification and compliance could experience service disruptions. Telecom operators (STC, Mobily) and media companies relying on content credentials for broadcast authentication are vulnerable. The lack of available patches creates sustained risk for critical infrastructure dependent on content verification systems.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Inventory all systems using Adobe C2PA (Rust and Node.js versions) across your organization
2. Isolate or air-gap critical C2PA instances from untrusted networks
3. Implement strict rate limiting on C2PA API endpoints (max 10 requests/second per IP)
4. Deploy network-level DDoS mitigation and resource monitoring
COMPENSATING CONTROLS:
5. Implement input validation and size limits on C2PA processing requests (max payload 10MB)
6. Configure resource quotas: CPU limits (50% max), memory limits (512MB per process), connection limits (100 concurrent)
7. Deploy Web Application Firewall (WAF) rules to detect resource exhaustion patterns
8. Enable comprehensive logging of C2PA requests with resource consumption metrics
DETECTION RULES:
9. Alert on sustained high CPU/memory usage from C2PA processes
10. Monitor for repeated failed C2PA validation attempts from single source
11. Track request patterns exceeding normal baseline by >300%
12. Implement timeout mechanisms (30-second max per request)
PATCHING STRATEGY:
13. Monitor Adobe security advisories for patch availability
14. Prepare upgrade plan to patched versions immediately upon release
15. Consider temporary migration to alternative content verification solutions if critical
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. قم بحصر جميع الأنظمة التي تستخدم Adobe C2PA (إصدارات Rust و Node.js) عبر مؤسستك
2. عزل أو فصل مثيلات C2PA الحرجة عن الشبكات غير الموثوقة
3. تطبيق تحديد معدل صارم على نقاط نهاية API الخاصة بـ C2PA (الحد الأقصى 10 طلبات/ثانية لكل عنوان IP)
4. نشر تخفيف DDoS على مستوى الشبكة ومراقبة الموارد
الضوابط التعويضية:
5. تطبيق التحقق من صحة المدخلات وحدود الحجم على طلبات معالجة C2PA (الحد الأقصى للحمولة 10 ميجابايت)
6. تكوين حصص الموارد: حدود CPU (50% كحد أقصى)، حدود الذاكرة (512 ميجابايت لكل عملية)، حدود الاتصال (100 متزامن)
7. نشر قواعد جدار حماية تطبيقات الويب (WAF) للكشف عن أنماط استنزاف الموارد
8. تفعيل تسجيل شامل لطلبات C2PA مع مقاييس استهلاك الموارد
قواعد الكشف:
9. تنبيه على استخدام CPU/الذاكرة المرتفع المستمر من عمليات C2PA
10. مراقبة محاولات التحقق الفاشلة المتكررة من C2PA من مصدر واحد
11. تتبع أنماط الطلب التي تتجاوز خط الأساس الطبيعي بنسبة >300%
12. تطبيق آليات المهلة الزمنية (30 ثانية كحد أقصى لكل طلب)
استراتيجية التصحيح:
13. مراقبة نشرات أمان Adobe لتوفر التصحيحات
14. تحضير خطة الترقية إلى الإصدارات المصححة فوراً عند إصدارها
15. النظر في الهجرة المؤقتة إلى حلول التحقق من المحتوى البديلة إذا كانت حرجة
