📄 Description (English)

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.0, a Server-Side Request Forgery (SSRF) protection bypass vulnerability exists in the Custom Function feature. While the application implements SSRF protection via HTTP_DENY_LIST for axios and node-fetch libraries, the built-in Node.js http, https, and net modules are allowed in the NodeVM sandbox without equivalent protection. This allows authenticated users to bypass SSRF controls and access internal network resources (e.g., cloud provider metadata services) This vulnerability is fixed in 3.1.0.

🤖 AI Executive Summary

Flowise versions prior to 3.1.0 contain an SSRF bypass vulnerability in the Custom Function feature that allows authenticated users to access internal network resources using Node.js built-in modules. The vulnerability exists because HTTP_DENY_LIST protection is not applied to http, https, and net modules in the NodeVM sandbox.

📄 Description (Arabic)

تتعلق الثغرة بعدم تطبيق قائمة الحظر على وحدات Node.js المدمجة (http و https و net) في بيئة NodeVM المعزولة. يمكن للمستخدمين المصرح لهم استخدام هذه الوحدات للوصول إلى خدمات البيانات الوصفية للسحابة والموارد الداخلية الأخرى. تم إصلاح هذه الثغرة في الإصدار 3.1.0.

🤖 ملخص تنفيذي (AI)

تحتوي إصدارات Flowise السابقة للإصدار 3.1.0 على ثغرة تجاوز SSRF في ميزة الدالة المخصصة تسمح للمستخدمين المصرح لهم بالوصول إلى موارد الشبكة الداخلية. الثغرة موجودة لأن حماية HTTP_DENY_LIST لم تُطبق على وحدات http و https و net في صندوق NodeVM.

🔧 Remediation Steps (English)
Upgrade Flowise to version 3.1.0 or later immediately. Implement network segmentation to restrict access from application servers to internal resources. Apply additional firewall rules to block unauthorized access to cloud metadata services and internal APIs. Review and audit all custom functions for potential misuse.
🔧 خطوات المعالجة (العربية)
قم بترقية Flowise إلى الإصدار 3.1.0 أو أحدث فوراً. طبق تقسيم الشبكة لتقييد الوصول من خوادم التطبيقات إلى الموارد الداخلية. طبق قواعد جدار حماية إضافية لحظر الوصول غير المصرح به إلى خدمات البيانات الوصفية السحابية والواجهات البرمجية الداخلية. راجع وتدقيق جميع الدوال المخصصة للاستخدام المحتمل الخاطئ.
