📄 Description (English)
Grav is a file-based Web platform. Prior to 2.0.0-beta.2, a stored Cross-Site Scripting (XSS) vulnerability in getgrav/grav allows publisher-level accounts to execute arbitrary JavaScript. The issue arises from a blacklist bypass in the detectXss() function when handling unquoted HTML event attributes. This vulnerability is fixed in 2.0.0-beta.2.
🤖 AI Executive Summary
A stored Cross-Site Scripting (XSS) vulnerability in Grav CMS versions prior to 2.0.0-beta.2 allows publisher-level accounts to execute arbitrary JavaScript through a blacklist bypass in the detectXss() function. With a CVSS score of 8.5 and publicly available exploits, this poses a significant risk to organizations using Grav for content management. Immediate patching to version 2.0.0-beta.2 or later is critical to prevent account compromise and data theft.

🇸🇦 Saudi Arabia Impact Assessment
Saudi organizations using Grav CMS for government portals, corporate websites, and content management systems are at risk. Most vulnerable sectors include: Government agencies (NCA, CITC) using Grav for public-facing portals; Banking and financial institutions using Grav for customer-facing content; Healthcare organizations (MOH) managing patient information portals; Educational institutions (universities) hosting course content; Media and publishing companies. The stored XSS vulnerability allows attackers with publisher privileges to inject malicious scripts that execute in administrators' browsers, potentially leading to credential theft, session hijacking, and unauthorized administrative actions.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all Grav installations in your environment and document their versions
2. Restrict publisher account access to trusted personnel only
3. Implement Content Security Policy (CSP) headers to mitigate XSS impact
4. Enable security logging for all content modifications
PATCHING:
1. Upgrade Grav to version 2.0.0-beta.2 or later immediately
2. For installations unable to upgrade immediately, apply the detectXss() function patch from the official Grav repository
3. Test patches in staging environment before production deployment
COMPENSATING CONTROLS:
1. Implement Web Application Firewall (WAF) rules to detect and block XSS payloads in unquoted HTML attributes
2. Use input validation to reject content containing event attributes (onclick, onload, onerror, etc.)
3. Enforce output encoding for all user-generated content
4. Implement strict RBAC limiting publisher permissions
DETECTION:
1. Monitor for suspicious JavaScript in page content using SIEM rules
2. Alert on modifications to core Grav files or detectXss() function
3. Track publisher account activities and content changes
4. Search logs for patterns: 'on[a-z]*=' in unquoted attributes
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. حدد جميع تثبيتات Grav في بيئتك وقم بتوثيق إصداراتها
2. قيد الوصول إلى حسابات الناشر للموظفين الموثوقين فقط
3. طبق رؤوس سياسة أمان المحتوى (CSP) للتخفيف من تأثير XSS
4. فعّل تسجيل الأمان لجميع تعديلات المحتوى
التصحيح:
1. قم بترقية Grav إلى الإصدار 2.0.0-beta.2 أو أحدث فوراً
2. بالنسبة للتثبيتات غير القادرة على الترقية فوراً، طبق تصحيح دالة detectXss() من مستودع Grav الرسمي
3. اختبر التصحيحات في بيئة التطوير قبل نشرها في الإنتاج
الضوابط البديلة:
1. طبق قواعد جدار حماية تطبيقات الويب (WAF) للكشف عن حمولات XSS وحظرها في السمات غير المقتبسة
2. استخدم التحقق من الإدخال لرفض المحتوى الذي يحتوي على سمات الأحداث (onclick, onload, onerror، إلخ)
3. فرض ترميز الإخراج لجميع المحتوى الذي ينشئه المستخدم
4. طبق RBAC صارم يحد من صلاحيات الناشر
الكشف:
1. راقب JavaScript المريب في محتوى الصفحة باستخدام قواعد SIEM
2. أصدر تنبيهات عند تعديل ملفات Grav الأساسية أو دالة detectXss()
3. تتبع أنشطة حسابات الناشر وتغييرات المحتوى
4. ابحث في السجلات عن الأنماط: 'on[a-z]*=' في السمات غير المقتبسة
