📄 الوصف (الإنجليزية)
The The Advanced Custom Fields: Extended plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 0.9.2.3. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Disable the Advanced Custom Fields: Extended plugin immediately across all WordPress installations
2. Audit WordPress access logs for suspicious shortcode execution patterns (look for do_shortcode calls with unusual parameters)
3. Scan website content for injected shortcodes or malicious code
4. Review user accounts for unauthorized access or privilege escalation
PATCHING GUIDANCE:
1. Monitor plugin repository for security updates (currently no patch available)
2. Consider alternative ACF plugins with better security track records
3. If plugin functionality is critical, implement Web Application Firewall (WAF) rules to block shortcode injection attempts
COMPENSATING CONTROLS:
1. Deploy WAF rules blocking requests containing suspicious shortcode patterns: [[\ and do_shortcode variations
2. Implement strict Content Security Policy (CSP) headers to prevent inline script execution
3. Enable WordPress security plugins (Wordfence, Sucuri) with real-time malware scanning
4. Restrict plugin execution to authenticated users only via .htaccess or nginx configuration
5. Implement file integrity monitoring on wp-content/plugins directory
DETECTION RULES:
1. Monitor for POST/GET requests containing shortcode syntax: [[\ patterns
2. Alert on do_shortcode function calls in error logs
3. Track modifications to wp_options table for injected shortcodes
4. Monitor for unusual outbound connections from WordPress process
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تعطيل مكون Advanced Custom Fields: Extended فوراً عبر جميع تثبيتات WordPress
2. تدقيق سجلات الوصول للبحث عن أنماط تنفيذ shortcode مريبة
3. فحص محتوى الموقع للبحث عن shortcodes مُدرجة أو أكواد ضارة
4. مراجعة حسابات المستخدمين للكشف عن الوصول غير المصرح به
إرشادات التصحيح:
1. مراقبة مستودع المكونات للتحديثات الأمنية
2. النظر في بدائل ACF بسجلات أمان أفضل
3. إذا كانت وظيفة المكون حرجة، تطبيق قواعد جدار الحماية (WAF)
الضوابط التعويضية:
1. نشر قواعد WAF لحظر طلبات shortcode المريبة
2. تطبيق رؤوس Content Security Policy (CSP) صارمة
3. تفعيل مكونات أمان WordPress (Wordfence, Sucuri)
4. تقييد تنفيذ المكونات للمستخدمين المصرح لهم فقط
5. تطبيق مراقبة سلامة الملفات على دليل wp-content/plugins
قواعد الكشف:
1. مراقبة الطلبات التي تحتوي على بناء جملة shortcode
2. التنبيه على استدعاءات do_shortcode في السجلات
3. تتبع التعديلات على جدول wp_options
4. مراقبة الاتصالات الخارجية غير العادية
