📄 الوصف (الإنجليزية)
A vulnerability was found in OpenBMB XAgent 1.0.0. This impacts the function check_user of the file XAgentServer/application/websockets/share.py of the component ShareServer WebSocket Endpoint. Performing a manipulation of the argument interaction_id results in missing authentication. Remote exploitation of the attack is possible. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.
🤖 ملخص AI
CVE-2026-4959 is a critical authentication bypass vulnerability in OpenBMB XAgent 1.0.0's ShareServer WebSocket endpoint that allows remote attackers to manipulate the interaction_id parameter to bypass user authentication checks. With a CVSS score of 7.3 and public exploit availability, this vulnerability poses significant risk to organizations deploying XAgent for AI-powered automation tasks. The vendor's non-responsiveness and lack of available patches elevate the urgency for immediate mitigation.

🇸🇦 التأثير على المملكة العربية السعودية
Saudi organizations in government digital transformation initiatives, financial services automation, and healthcare AI implementations using OpenBMB XAgent are at direct risk. SAMA-regulated financial institutions deploying XAgent for transaction processing or customer service automation face authentication bypass risks. Government agencies (NCA, CITC) utilizing XAgent for administrative automation could experience unauthorized access to sensitive systems. Healthcare providers using XAgent for patient data processing face HIPAA-equivalent compliance violations. Telecom operators (STC, Mobily) implementing XAgent for customer service could expose subscriber data. Energy sector organizations (ARAMCO, SEC) using XAgent for operational technology integration face critical infrastructure risks.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all instances of OpenBMB XAgent 1.0.0 in your environment using network scanning and asset inventory tools
2. Isolate affected XAgent deployments from production networks or disable ShareServer WebSocket endpoints immediately
3. Review access logs for suspicious interaction_id manipulation patterns (unusual parameter values, repeated failed authentication attempts)
4. Revoke all active sessions and force re-authentication for users who accessed XAgent during the vulnerability window
COMPENSATING CONTROLS (until patch available):
5. Implement network-level access controls restricting WebSocket connections to ShareServer endpoint to trusted IP ranges only
6. Deploy WAF/API gateway rules to validate interaction_id format and reject malformed parameters
7. Enable comprehensive logging and monitoring of all ShareServer WebSocket authentication attempts
8. Implement rate limiting on authentication endpoints to prevent brute-force exploitation
9. Use reverse proxy authentication layer to enforce additional authentication before reaching XAgent
DETECTION RULES:
10. Monitor for POST/WebSocket requests to /share.py endpoints with non-standard interaction_id values
11. Alert on authentication bypass patterns: successful access without valid credentials or with manipulated interaction_id
12. Track failed authentication attempts followed by successful access with different interaction_id values
13. Monitor for lateral movement from XAgent to other internal systems post-exploitation
LONG-TERM:
14. Evaluate alternative AI automation platforms with better security track records
15. Plan migration away from OpenBMB XAgent 1.0.0 to patched versions or alternative solutions
16. Implement zero-trust architecture for all AI/automation platform access
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع حالات OpenBMB XAgent 1.0.0 في بيئتك باستخدام أدوات المسح والمخزون
2. عزل نشرات XAgent المتأثرة عن شبكات الإنتاج أو تعطيل نقاط نهاية ShareServer WebSocket فوراً
3. مراجعة سجلات الوصول للبحث عن أنماط معالجة interaction_id المريبة
4. إلغاء جميع الجلسات النشطة وفرض إعادة المصادقة للمستخدمين
الضوابط البديلة:
5. تنفيذ ضوابط الوصول على مستوى الشبكة لتقييد اتصالات WebSocket إلى نطاقات IP موثوقة
6. نشر قواعد WAF/API gateway للتحقق من صيغة interaction_id
7. تفعيل السجلات الشاملة ومراقبة محاولات المصادقة
8. تنفيذ تحديد معدل على نقاط نهاية المصادقة
9. استخدام طبقة مصادقة reverse proxy إضافية
قواعد الكشف:
10. مراقبة طلبات WebSocket إلى نقاط نهاية /share.py بقيم interaction_id غير قياسية
11. التنبيه على أنماط تجاوز المصادقة
12. تتبع محاولات المصادقة الفاشلة متبوعة بالوصول الناجح
13. مراقبة الحركة الجانبية من XAgent إلى الأنظمة الداخلية الأخرى
المدى الطويل:
14. تقييم منصات أتمتة ذكاء اصطناعي بديلة
15. التخطيط للهجرة بعيداً عن OpenBMB XAgent 1.0.0
16. تنفيذ معمارية zero-trust لجميع منصات الذكاء الاصطناعي
