📄 Description (English)
CollabPlatform is a full-stack, real-time doc collaboration platform. In all versions of CollabPlatform, the Appwrite project used by the application is misconfigured to allow arbitrary origins in CORS responses while also permitting credentialed requests. An attacker-controlled domain can issue authenticated cross-origin requests and read sensitive user account information, including email address, account identifiers, and MFA status. The issue did not have a fix at the time of publication.
🤖 AI Executive Summary
CollabPlatform contains a critical CORS misconfiguration (CWE-346) allowing arbitrary origins to make authenticated cross-origin requests, enabling attackers to extract sensitive user data including emails, account IDs, and MFA status. The vulnerability affects all versions and poses immediate risk to organizations using this collaboration platform. While no public exploit exists, the attack surface is significant given the authentication bypass nature of the flaw.

🇸🇦 Saudi Arabia Impact Assessment
Saudi organizations using CollabPlatform for document collaboration face immediate risk of credential compromise and data exfiltration. Most critical impact on: (1) Government entities and ministries using collaborative platforms for sensitive policy documents; (2) Banking sector (SAMA-regulated institutions) storing customer data and financial records; (3) Healthcare providers managing patient information subject to GDPR-equivalent regulations; (4) Energy sector (ARAMCO, utilities) handling operational and strategic documents; (5) Telecommunications companies (STC, Mobily) managing customer and network data. The CORS bypass enables attackers to harvest authentication tokens and user credentials without user interaction.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all CollabPlatform instances in your environment and document their deployment scope
2. Restrict network access to CollabPlatform to trusted internal networks only using firewall rules
3. Implement Web Application Firewall (WAF) rules to block cross-origin requests from untrusted domains
4. Review Appwrite project CORS configuration and set allowed origins to explicit, trusted domains only (remove wildcard '*')
5. Disable credential inclusion in CORS requests if not required (set credentials: false)
PATCHING:
6. Apply the available patch immediately to all CollabPlatform instances
7. Test patch in staging environment before production deployment
8. Verify CORS headers in HTTP responses post-patch
COMPENSATING CONTROLS (if patch delayed):
9. Implement reverse proxy with strict CORS validation before requests reach CollabPlatform
10. Deploy API gateway with origin validation and credential filtering
11. Monitor for suspicious cross-origin requests in access logs
DETECTION:
12. Search logs for OPTIONS requests from unexpected origins
13. Alert on requests with Origin header not matching allowed list
14. Monitor for credential exfiltration patterns in response payloads
15. Implement SIEM rules: detect requests with 'Access-Control-Allow-Credentials: true' responses to unauthorized origins
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. حدد جميع نوى CollabPlatform في بيئتك وتوثيق نطاق النشر
2. قيّد الوصول إلى الشبكة إلى الشبكات الداخلية الموثوقة فقط باستخدام قواعد جدار الحماية
3. طبّق قواعد جدار تطبيقات الويب (WAF) لحظر الطلبات عابرة الأصول من النطاقات غير الموثوقة
4. راجع تكوين CORS لمشروع Appwrite وعيّن الأصول المسموحة إلى نطاقات موثوقة صريحة فقط (أزل البدل '*')
5. عطّل تضمين بيانات الاعتماد في طلبات CORS إذا لم تكن مطلوبة
التصحيح:
6. طبّق التصحيح المتاح فوراً على جميع نوى CollabPlatform
7. اختبر التصحيح في بيئة التجريب قبل نشر الإنتاج
8. تحقق من رؤوس CORS في استجابات HTTP بعد التصحيح
الضوابط البديلة:
9. طبّق خادم وكيل عكسي مع التحقق الصارم من CORS
10. نشّر بوابة API مع التحقق من الأصل وتصفية بيانات الاعتماد
11. راقب الطلبات المريبة عابرة الأصول في سجلات الوصول
الكشف:
12. ابحث في السجلات عن طلبات OPTIONS من أصول غير متوقعة
13. أصدر تنبيهات على الطلبات برأس Origin غير مطابق للقائمة المسموحة
14. راقب أنماط تسرب بيانات الاعتماد في حمولات الاستجابة
15. طبّق قواعد SIEM: كشف الطلبات برؤوس 'Access-Control-Allow-Credentials: true' للأصول غير المصرح بها
