📄 Description (English)
OpenClaw versions 2026.4.5 before 2026.4.10 contain a sandbox escape vulnerability allowing sandboxed agents to override exec routing by specifying host=node. Attackers can bypass sandbox boundaries and route execution to remote nodes instead of intended sandbox paths.
🤖 AI Executive Summary
OpenClaw versions 2026.4.5 through 2026.4.9 contain a critical sandbox escape vulnerability (CVE-2026-42434) that allows sandboxed agents to bypass execution boundaries by manipulating host routing parameters. Attackers can redirect command execution to unintended remote nodes, potentially compromising isolated environments. This vulnerability poses significant risk to organizations using OpenClaw for containerized or isolated workload management, particularly in multi-tenant environments.

🇸🇦 Saudi Arabia Impact Assessment
Saudi organizations leveraging OpenClaw for containerized microservices, particularly in banking (SAMA-regulated institutions), government cloud infrastructure (NCA oversight), healthcare systems, and energy sector operations face significant risk. The vulnerability enables lateral movement and privilege escalation within isolated environments. Banking sector exposure is highest due to reliance on containerized transaction processing systems. Government agencies using OpenClaw for secure workload isolation are at risk of unauthorized access to classified processing environments. Telecom operators (STC, Mobily) using OpenClaw for network function virtualization could experience service disruption and data exfiltration.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all OpenClaw deployments in your environment and document versions (2026.4.5-2026.4.9 are vulnerable)
2. Isolate affected OpenClaw instances from production networks if possible
3. Implement network segmentation to restrict inter-node communication
4. Enable comprehensive audit logging for all agent-to-node routing requests
PATCHING GUIDANCE:
1. Upgrade to OpenClaw 2026.4.10 or later immediately when available
2. Verify patch integrity using vendor-provided checksums
3. Test patches in non-production environments first
4. Plan phased rollout to minimize service disruption
COMPENSATING CONTROLS (until patch available):
1. Implement strict input validation on host parameter specifications
2. Deploy WAF/API gateway rules to block host=node patterns in agent requests
3. Restrict agent execution permissions using RBAC policies
4. Monitor and alert on any host parameter modifications in agent configurations
5. Implement network policies to prevent agents from initiating connections to unauthorized nodes
DETECTION RULES:
1. Alert on any agent requests containing 'host=node' or similar routing overrides
2. Monitor for unexpected inter-node communication patterns from sandboxed agents
3. Track failed sandbox boundary enforcement attempts
4. Log all agent configuration changes, particularly host/routing parameters
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. حدد جميع نشرات OpenClaw في بيئتك وقثق الإصدارات (2026.4.5-2026.4.9 معرضة للخطر)
2. عزل مثيلات OpenClaw المتأثرة عن شبكات الإنتاج إن أمكن
3. تطبيق تقسيم الشبكة لتقييد الاتصالات بين العقد
4. تفعيل تسجيل التدقيق الشامل لجميع طلبات توجيه الوكيل إلى العقدة
إرشادات التصحيح:
1. الترقية إلى OpenClaw 2026.4.10 أو إصدار أحدث فوراً عند توفره
2. التحقق من سلامة التصحيح باستخدام المجاميع المرجعية المقدمة من البائع
3. اختبار التصحيحات في بيئات غير الإنتاج أولاً
4. التخطيط للنشر المرحلي لتقليل انقطاع الخدمة
الضوابط البديلة (حتى توفر التصحيح):
1. تطبيق التحقق الصارم من المدخلات على مواصفات معاملات المضيف
2. نشر قواعد WAF/بوابة API لحظر أنماط host=node في طلبات الوكيل
3. تقييد أذونات تنفيذ الوكيل باستخدام سياسات RBAC
4. مراقبة والتنبيه على أي تعديلات معاملات المضيف في تكوينات الوكيل
5. تطبيق سياسات الشبكة لمنع الوكلاء من بدء الاتصالات بالعقد غير المصرح بها
قواعد الكشف:
1. التنبيه على أي طلبات وكيل تحتوي على 'host=node' أو تجاوزات توجيه مماثلة
2. مراقبة أنماط الاتصالات غير المتوقعة بين العقد من الوكلاء المعزولين
3. تتبع محاولات فرض حدود الحماية الرملية الفاشلة
4. تسجيل جميع تغييرات تكوين الوكيل، خاصة معاملات المضيف/التوجيه
