📄 Description (English)
A vulnerability was detected in PromtEngineer localGPT up to 4d41c7d1713b16b216d8e062e51a5dd88b20b054. Impacted is the function LocalGPTHandler of the file backend/server.py of the component API Endpoint. The manipulation of the argument BaseHTTPRequestHandler results in missing authentication. The attack can be executed remotely. This product implements a rolling release for ongoing delivery, which means version information for affected or updated releases is unavailable. The vendor was contacted early about this disclosure but did not respond in any way.
🤖 AI Executive Summary
CVE-2026-5000 is a critical authentication bypass vulnerability in PromtEngineer localGPT affecting the API endpoint handler. The flaw allows remote attackers to bypass authentication mechanisms through manipulation of the BaseHTTPRequestHandler argument, potentially enabling unauthorized access to AI model inference capabilities. With no patch available and the vendor unresponsive, immediate compensating controls are essential for organizations deploying this software.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Inventory all instances of PromtEngineer localGPT across your infrastructure and isolate affected systems from production networks
2. Implement network-level access controls restricting API endpoint access to authorized IP ranges only
3. Deploy Web Application Firewall (WAF) rules to detect and block suspicious BaseHTTPRequestHandler manipulation attempts
4. Enable comprehensive API logging and monitoring for all authentication-related events
COMPENSATING CONTROLS:
5. Implement reverse proxy authentication layer (e.g., OAuth2, SAML) in front of localGPT API endpoints
6. Deploy API gateway with mandatory token-based authentication and rate limiting
7. Segment localGPT instances within zero-trust network architecture
8. Implement mutual TLS (mTLS) for all API communications
DETECTION RULES:
9. Monitor for HTTP requests with malformed or missing authentication headers to /api/* endpoints
10. Alert on successful API calls without valid authentication tokens
11. Track BaseHTTPRequestHandler instantiation patterns in application logs
12. Implement behavioral analysis for unusual API access patterns
LONG-TERM:
13. Evaluate alternative AI inference solutions with active security support
14. Plan migration away from localGPT to vendor-supported alternatives
15. Conduct security code review of any custom modifications to localGPT
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. قم بحصر جميع حالات PromtEngineer localGPT عبر البنية التحتية الخاصة بك وعزل الأنظمة المتأثرة عن شبكات الإنتاج
2. تنفيذ ضوابط الوصول على مستوى الشبكة لتقييد وصول نقطة نهاية API إلى نطاقات IP المصرح بها فقط
3. نشر قواعد جدار حماية تطبيقات الويب (WAF) للكشف عن محاولات التلاعب بـ BaseHTTPRequestHandler وحجبها
4. تفعيل السجلات الشاملة ومراقبة جميع الأحداث المتعلقة بالمصادقة
الضوابط التعويضية:
5. تنفيذ طبقة مصادقة وكيل عكسي (مثل OAuth2 و SAML) أمام نقاط نهاية API الخاصة بـ localGPT
6. نشر بوابة API مع مصادقة إلزامية قائمة على الرموز وتحديد معدل الطلب
7. تقسيم حالات localGPT ضمن معمارية شبكة الثقة الصفرية
8. تنفيذ TLS المتبادل (mTLS) لجميع اتصالات API
قواعد الكشف:
9. مراقبة طلبات HTTP بـ headers مصادقة مشوهة أو مفقودة إلى نقاط نهاية /api/*
10. تنبيهات على استدعاءات API الناجحة بدون رموز مصادقة صحيحة
11. تتبع أنماط إنشاء BaseHTTPRequestHandler في سجلات التطبيق
12. تنفيذ التحليل السلوكي لأنماط الوصول غير العادية إلى API
المدى الطويل:
13. تقييم حلول استدلال الذكاء الاصطناعي البديلة مع دعم أمان نشط
14. التخطيط للهجرة بعيداً عن localGPT إلى بدائل مدعومة من البائع
15. إجراء مراجعة أمان الكود لأي تعديلات مخصصة على localGPT
