📄 Description (English)
prompts.chat prior to commit 1464475 contains an identity confusion vulnerability due to inconsistent case-sensitive and case-insensitive handling of usernames across write and read paths, allowing attackers to create case-variant usernames that bypass uniqueness checks. Attackers can exploit non-deterministic username resolution to impersonate victim accounts, replace profile content on canonical URLs, and inject attacker-controlled metadata and content across the platform.
🤖 AI Executive Summary
CVE-2026-22665 is a critical identity confusion vulnerability in prompts.chat that allows attackers to bypass username uniqueness checks through case-variant manipulation. Attackers can create accounts with usernames differing only in case (e.g., 'Admin' vs 'admin'), leading to account impersonation, profile hijacking, and unauthorized content injection. With no patch currently available and high CVSS score of 8.1, this poses immediate risk to users and organizations relying on prompts.chat for identity-dependent operations.

🇸🇦 Saudi Arabia Impact Assessment
This vulnerability primarily impacts Saudi organizations using prompts.chat for AI-driven content generation, customer service automation, and knowledge management. Most at-risk sectors include: Government agencies (NCA, CITC) using the platform for official communications; Banking and Financial Services (SAMA-regulated entities) for customer interaction systems; Telecommunications (STC, Mobily) for chatbot services; Healthcare providers using AI for patient engagement; and Educational institutions. The identity confusion vulnerability could lead to unauthorized access to sensitive organizational accounts, impersonation of official representatives, and injection of malicious content into customer-facing systems.

🔧 Remediation Steps (English)
Immediate Actions:
1. Audit all user accounts on prompts.chat for case-variant duplicates (e.g., 'Admin', 'admin', 'ADMIN') and document findings
2. Disable or restrict account creation functionality until patch is available
3. Implement emergency access controls: require multi-factor authentication for all accounts, especially administrative ones
4. Monitor for suspicious login patterns and case-variant username creation attempts
Compensating Controls (until patch available):
5. Normalize all usernames to lowercase in authentication logic at application layer
6. Implement strict username validation: reject usernames that differ only in case from existing accounts
7. Add logging and alerting for any username resolution mismatches
8. Restrict profile modification permissions to verified identity verification methods
9. Implement content integrity checks on profile pages
Detection Rules:
10. Alert on login attempts using case-variant usernames
11. Monitor for profile content changes from unexpected IP addresses or sessions
12. Track database queries showing case-insensitive username matches
13. Flag any account creation attempts within 24 hours of similar usernames
Long-term:
14. Await and immediately apply vendor patch when available
15. Conduct full security audit of identity management systems post-patch
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تدقيق جميع حسابات المستخدمين على prompts.chat للبحث عن نسخ مكررة تختلف في حالة الأحرف وتوثيق النتائج
2. تعطيل أو تقييد وظيفة إنشاء الحسابات حتى يتوفر التصحيح
3. تطبيق ضوابط وصول طارئة: طلب المصادقة متعددة العوامل لجميع الحسابات خاصة الإدارية
4. مراقبة أنماط تسجيل الدخول المريبة ومحاولات إنشاء أسماء مستخدمين متغيرة الحالة
الضوابط البديلة (حتى يتوفر التصحيح):
5. تطبيع جميع أسماء المستخدمين إلى أحرف صغيرة في منطق المصادقة
6. تطبيق التحقق الصارم من اسم المستخدم: رفض الأسماء التي تختلف فقط في الحالة
7. إضافة تسجيل والتنبيهات لعدم تطابق دقة اسم المستخدم
8. تقييد صلاحيات تعديل الملف الشخصي
9. تطبيق فحوصات سلامة المحتوى على صفحات الملف الشخصي
قواعد الكشف:
10. التنبيه على محاولات تسجيل الدخول باستخدام أسماء مستخدمين متغيرة الحالة
11. مراقبة تغييرات محتوى الملف الشخصي من عناوين IP أو جلسات غير متوقعة
12. تتبع استعلامات قاعدة البيانات التي تظهر عدم تطابق حالة اسم المستخدم
13. وضع علامة على محاولات إنشاء حسابات خلال 24 ساعة من أسماء متشابهة
المدى الطويل:
14. انتظر وطبق التصحيح الفوري عند توفره
15. إجراء تدقيق أمني شامل لأنظمة إدارة الهوية بعد التصحيح
