📄 Description (English)
A vulnerability was determined in FoundationAgents MetaGPT up to 0.8.2. Affected by this issue is the function check_cmd_exists of the file metagpt/utils/common.py. This manipulation of the argument mermaid.path causes command injection. The attack may be initiated remotely. A high degree of complexity is needed for the attack. The exploitation is known to be difficult. The exploit has been publicly disclosed and may be utilized. The project was informed of the problem early through an issue report but has not responded yet.
🤖 AI Executive Summary
CVE-2026-11455 is a command injection vulnerability in FoundationAgents MetaGPT versions up to 0.8.2 affecting the check_cmd_exists function. While the CVSS score is moderate (5.0), the vulnerability requires high complexity to exploit and no public exploit is currently available. Organizations using MetaGPT for AI-driven development or automation should assess their exposure and implement compensating controls until patches are released.

🔧 Remediation Steps (English)
Immediate Actions:
1. Inventory all MetaGPT installations across development and production environments
2. Restrict network access to MetaGPT services to trusted internal networks only
3. Disable or isolate the mermaid.path parameter functionality if not critical to operations
4. Implement input validation and sanitization for all mermaid.path parameters
Patching Guidance:
1. Monitor FoundationAgents GitHub repository for security patches
2. When patches become available, prioritize updating to the latest patched version
3. Test patches in isolated development environments before production deployment
Compensating Controls:
1. Run MetaGPT in containerized environments with restricted system permissions
2. Implement Web Application Firewall (WAF) rules to block suspicious mermaid.path parameters
3. Enable command execution logging and monitoring on systems running MetaGPT
4. Use SELinux or AppArmor to restrict MetaGPT process capabilities
5. Implement network segmentation to isolate MetaGPT services
Detection Rules:
1. Monitor for unusual process execution spawned from MetaGPT processes
2. Alert on mermaid.path parameters containing shell metacharacters (;, |, &, $, `, etc.)
3. Log and review all command execution attempts from check_cmd_exists function
4. Monitor for unexpected outbound connections from MetaGPT services
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. حصر جميع تثبيتات MetaGPT عبر بيئات التطوير والإنتاج
2. تقييد الوصول الشبكي لخدمات MetaGPT للشبكات الداخلية الموثوقة فقط
3. تعطيل أو عزل وظيفة معامل mermaid.path إذا لم تكن حرجة للعمليات
4. تطبيق التحقق من صحة المدخلات وتنظيفها لجميع معاملات mermaid.path
إرشادات التصحيح:
1. مراقبة مستودع FoundationAgents GitHub للحصول على تصحيحات الأمان
2. عند توفر التصحيحات، أولويات التحديث إلى أحدث إصدار مصحح
3. اختبار التصحيحات في بيئات التطوير المعزولة قبل نشرها في الإنتاج
الضوابط التعويضية:
1. تشغيل MetaGPT في بيئات حاويات مع أذونات نظام مقيدة
2. تطبيق قواعد جدار الحماية لتطبيقات الويب (WAF) لحجب معاملات mermaid.path المريبة
3. تفعيل تسجيل ومراقبة تنفيذ الأوامر على الأنظمة التي تشغل MetaGPT
4. استخدام SELinux أو AppArmor لتقييد قدرات عملية MetaGPT
5. تطبيق تقسيم الشبكة لعزل خدمات MetaGPT
قواعد الكشف:
1. مراقبة تنفيذ العمليات غير العادية التي تنشأ من عمليات MetaGPT
2. التنبيه على معاملات mermaid.path التي تحتوي على أحرف shell (;, |, &, $, `, إلخ)
3. تسجيل ومراجعة جميع محاولات تنفيذ الأوامر من دالة check_cmd_exists
4. مراقبة الاتصالات الخارجية غير المتوقعة من خدمات MetaGPT
