📄 Description (English)

IBM Langflow Desktop 1.0.0 through 1.8.4 IBM Langflow is vulnerable to server-side request forgery (SSRF). This may allow an authenticated attacker to send unauthorized requests from the system, potentially leading to network enumeration or facilitating other attacks.

🤖 AI Executive Summary

IBM Langflow Desktop versions 1.0.0 through 1.8.4 contain a server-side request forgery (SSRF) vulnerability that allows authenticated attackers to send unauthorized requests from the affected system. This vulnerability could enable network enumeration, lateral movement, or facilitate further attacks against internal infrastructure. While no public exploit is available, the lack of a patch and medium CVSS score (6.5) warrant immediate attention in Saudi organizations using this software.

📄 Description (Arabic)

🤖 AI Intelligence Analysis Analyzed: May 13, 2026 04:56
🇸🇦 Saudi Arabia Impact Assessment
Saudi organizations in financial services (banking sector under SAMA oversight), government agencies (NCA jurisdiction), and research institutions using IBM Langflow Desktop for AI/ML workflows face elevated risk. The SSRF vulnerability could enable attackers to enumerate internal network resources, access restricted services, or pivot to critical systems. Government entities and ARAMCO-affiliated organizations conducting AI research are particularly vulnerable. Telecom operators (STC, Mobily) using this tool for customer analytics may face data exposure risks.

🔧 Remediation Steps (English)
Immediate Actions:
1. Inventory all IBM Langflow Desktop installations across the organization and identify versions 1.0.0-1.8.4
2. Restrict network access to Langflow Desktop instances using firewall rules and network segmentation
3. Implement strict authentication controls and disable unnecessary user accounts with Langflow access
4. Monitor outbound connections from Langflow Desktop systems for suspicious requests

Patching Guidance:
1. Check IBM security advisories regularly for patch availability
2. If patch becomes available, prioritize deployment in non-production environments first
3. Consider upgrading to versions beyond 1.8.4 when available

Compensating Controls:
1. Deploy Web Application Firewall (WAF) rules to detect and block SSRF patterns
2. Implement egress filtering to restrict outbound connections to known-safe destinations only
3. Use network segmentation to isolate Langflow Desktop from sensitive internal systems
4. Enable detailed logging of all HTTP/HTTPS requests originating from Langflow instances
5. Implement request validation and URL whitelisting at the application level if possible

Detection Rules:
1. Monitor for unusual outbound connections from Langflow processes to internal IP ranges (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16)
2. Alert on requests to localhost, 127.0.0.1, or metadata service endpoints (169.254.169.254)
3. Track failed authentication attempts followed by SSRF-like request patterns
4. Monitor for requests to cloud provider metadata services or internal management interfaces
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. قم بحصر جميع تثبيتات IBM Langflow Desktop عبر المنظمة وحدد الإصدارات 1.0.0-1.8.4
2. قيد الوصول إلى الشبكة لمثيلات Langflow Desktop باستخدام قواعد جدار الحماية والفصل الشبكي
3. طبق عناصر تحكم مصادقة صارمة وعطل حسابات المستخدمين غير الضرورية التي تحتوي على وصول Langflow
4. راقب الاتصالات الصادرة من أنظمة Langflow Desktop للطلبات المريبة

إرشادات التصحيح:
1. تحقق من استشارات أمان IBM بانتظام لتوفر التصحيحات
2. إذا أصبح التصحيح متاحاً، أولوية النشر في بيئات غير الإنتاج أولاً
3. فكر في الترقية إلى إصدارات تتجاوز 1.8.4 عند توفرها

عناصر التحكم التعويضية:
1. نشر قواعد جدار تطبيقات الويب (WAF) للكشف عن أنماط SSRF وحجبها
2. تطبيق تصفية الخروج لتقييد الاتصالات الصادرة إلى الوجهات الآمنة المعروفة فقط
3. استخدم الفصل الشبكي لعزل Langflow Desktop عن الأنظمة الداخلية الحساسة
4. تفعيل تسجيل مفصل لجميع طلبات HTTP/HTTPS الناشئة من مثيلات Langflow
5. تطبيق التحقق من الطلب وإدراج عناوين URL البيضاء على مستوى التطبيق إن أمكن

قواعد الكشف:
1. راقب الاتصالات الصادرة غير العادية من عمليات Langflow إلى نطاقات IP الداخلية (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16)
2. تنبيه على الطلبات إلى localhost أو 127.0.0.1 أو نقاط نهاية خدمة البيانات الوصفية (169.254.169.254)
3. تتبع محاولات المصادقة الفاشلة متبوعة بأنماط طلبات تشبه SSRF
4. راقب الطلبات إلى خدمات البيانات الوصفية لمزود الخدمة السحابية أو واجهات الإدارة الداخلية
