📄 Description (English)
A weakness has been identified in atototo api-lab-mcp up to 0.2.1. This affects the function analyze_api_spec/generate_test_scenarios/test_http_endpoint of the file src/mcp/http-server.ts of the component HTTP Interface. This manipulation of the argument source/url causes server-side request forgery. The attack is possible to be carried out remotely. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
🤖 AI Executive Summary
CVE-2026-5832 is a Server-Side Request Forgery (SSRF) vulnerability in atototo api-lab-mcp versions up to 0.2.1 affecting the HTTP interface component. The vulnerability allows remote attackers to manipulate API specification analysis and test scenario generation functions to forge arbitrary server requests. With a CVSS score of 7.3 and public exploit availability, this poses a significant risk to organizations using this API testing framework, particularly those integrating it into development pipelines or CI/CD environments.

🇸🇦 Saudi Arabia Impact Assessment
Saudi organizations in the technology and financial sectors are at elevated risk. Banking institutions (SAMA-regulated) using api-lab-mcp for API testing and integration could face unauthorized access to internal systems and data exfiltration. Government agencies and critical infrastructure operators (NCA oversight) may experience lateral movement attacks if this tool is deployed in development environments. Telecommunications providers (STC, Mobily) and energy sector organizations (ARAMCO) utilizing this framework for API validation are vulnerable to internal network reconnaissance and potential compromise of backend services. The SSRF vulnerability could enable attackers to bypass network segmentation and access internal APIs, databases, and management interfaces not exposed to the internet.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all instances of atototo api-lab-mcp versions ≤0.2.1 in your environment, including development, testing, and CI/CD pipelines
2. Isolate affected systems from production networks and restrict network access to the HTTP interface
3. Review access logs for the analyze_api_spec, generate_test_scenarios, and test_http_endpoint functions for suspicious activity
4. Monitor for outbound connections from affected systems to unexpected internal or external destinations
PATCHING GUIDANCE:
1. Upgrade to api-lab-mcp version > 0.2.1 immediately when available (monitor project repository for updates)
2. If upgrade is not immediately possible, implement network-level controls:
- Restrict outbound connections from api-lab-mcp instances using firewall rules
- Implement egress filtering to block connections to internal IP ranges (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16)
- Use proxy/WAF to validate and sanitize API specification inputs
COMPENSATING CONTROLS:
1. Implement input validation on the 'source' and 'url' parameters - whitelist allowed domains and reject RFC1918 addresses
2. Deploy network segmentation to isolate api-lab-mcp from sensitive internal systems
3. Use service accounts with minimal privileges for api-lab-mcp execution
4. Implement request rate limiting and anomaly detection on HTTP interface endpoints
5. Disable or restrict the analyze_api_spec and generate_test_scenarios functions if not actively used
DETECTION RULES:
1. Monitor for HTTP requests to internal IP addresses (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, 127.0.0.1) originating from api-lab-mcp processes
2. Alert on unusual outbound connections from api-lab-mcp to cloud metadata services (169.254.169.254)
3. Log all API calls to analyze_api_spec, generate_test_scenarios, and test_http_endpoint with full parameter values
4. Monitor for error responses indicating failed SSRF attempts (connection timeouts, refused connections to internal systems)
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع حالات atototo api-lab-mcp الإصدارات ≤0.2.1 في بيئتك، بما في ذلك بيئات التطوير والاختبار وخطوط أنابيب CI/CD
2. عزل الأنظمة المتأثرة عن شبكات الإنتاج وتقييد الوصول إلى واجهة HTTP
3. مراجعة سجلات الوصول لوظائف analyze_api_spec و generate_test_scenarios و test_http_endpoint للنشاط المريب
4. مراقبة الاتصالات الصادرة من الأنظمة المتأثرة إلى وجهات داخلية أو خارجية غير متوقعة
توجيهات التصحيح:
1. الترقية إلى api-lab-mcp الإصدار > 0.2.1 فوراً عند توفره (مراقبة مستودع المشروع للتحديثات)
2. إذا لم تكن الترقية ممكنة على الفور، قم بتنفيذ عناصر تحكم على مستوى الشبكة:
- تقييد الاتصالات الصادرة من حالات api-lab-mcp باستخدام قواعد جدار الحماية
- تنفيذ تصفية الخروج لحظر الاتصالات بنطاقات IP الداخلية
- استخدام الوكيل/WAF للتحقق من صحة وتعقيم مدخلات مواصفات API
عناصر التحكم التعويضية:
1. تنفيذ التحقق من صحة الإدخال على معاملات 'source' و 'url' - قائمة بيضاء للمجالات المسموحة ورفض عناوين RFC1918
2. نشر تقسيم الشبكة لعزل api-lab-mcp عن الأنظمة الداخلية الحساسة
3. استخدام حسابات الخدمة بامتيازات محدودة لتنفيذ api-lab-mcp
4. تنفيذ تحديد معدل الطلب والكشف عن الشذوذ على نقاط نهاية واجهة HTTP
5. تعطيل أو تقييد وظائف analyze_api_spec و generate_test_scenarios إذا لم تكن قيد الاستخدام النشط
قواعد الكشف:
1. مراقبة طلبات HTTP إلى عناوين IP الداخلية الناشئة من عمليات api-lab-mcp
2. التنبيه على الاتصالات الصادرة غير العادية من api-lab-mcp إلى خدمات البيانات الوصفية للسحابة
3. تسجيل جميع استدعاءات API مع قيم المعاملات الكاملة
4. مراقبة استجابات الخطأ التي تشير إلى محاولات SSRF الفاشلة
