📄 Description (English)
The WP GDPR Cookie Consent plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'ninja_gdpr_ajax_actions' AJAX action in versions up to, and including, 1.0.0. This is due to missing capability and nonce checks on the handleAjaxCalls() function, combined with insufficient input sanitization on the gdprConfig values and missing output escaping in the generateCSS() function which echoes stored configuration values directly into a <style> block rendered on wp_head. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
🤖 AI Executive Summary
The WP GDPR Cookie Consent WordPress plugin (versions ≤1.0.0) contains a Stored Cross-Site Scripting (XSS) vulnerability allowing authenticated subscribers to inject malicious scripts via AJAX handlers. The vulnerability stems from missing capability checks, insufficient input sanitization, and improper output escaping in CSS generation. While currently unpatched, the medium CVSS score (6.4) and requirement for authenticated access limit immediate risk, but organizations using this plugin should prioritize remediation.

🇸🇦 Saudi Arabia Impact Assessment
Saudi organizations operating WordPress-based websites, particularly in government portals, banking customer-facing platforms, healthcare provider websites, and e-commerce sectors, are at risk. Government entities under NCA oversight and financial institutions regulated by SAMA face compliance implications if customer data is compromised through XSS attacks. The vulnerability is particularly concerning for organizations collecting GDPR-related consent data or operating multi-tenant WordPress environments where subscriber accounts may be compromised or delegated to third parties.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Audit all WordPress installations for WP GDPR Cookie Consent plugin presence and version (≤1.0.0)
2. Disable or deactivate the plugin immediately if no patch is available
3. Review user access logs for suspicious AJAX requests to 'ninja_gdpr_ajax_actions' endpoint
4. Check for injected malicious scripts in wp_head output and CSS style blocks
PATCHING GUIDANCE:
1. Contact plugin developer for security patch availability timeline
2. If patch becomes available, test in staging environment before production deployment
3. Implement Web Application Firewall (WAF) rules to block AJAX requests to vulnerable endpoints
COMPENSATING CONTROLS:
1. Restrict subscriber-level user creation; audit existing subscriber accounts
2. Implement Content Security Policy (CSP) headers to prevent inline script execution
3. Deploy WordPress security plugins (Wordfence, Sucuri) with XSS detection rules
4. Enable WordPress nonce verification on all AJAX handlers via custom code review
5. Implement input validation and output escaping on all GDPR configuration values
6. Monitor wp_head output for suspicious style tags or script injections
DETECTION RULES:
1. Monitor POST requests to /wp-admin/admin-ajax.php?action=ninja_gdpr_ajax_actions
2. Alert on any modifications to gdprConfig values from subscriber accounts
3. Scan wp_head output for <style> tags containing suspicious JavaScript or event handlers
4. Monitor database for serialized data in GDPR plugin options containing script tags
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تدقيق جميع تثبيتات WordPress للتحقق من وجود مكون WP GDPR Cookie Consent والإصدار (≤1.0.0)
2. تعطيل أو إلغاء تفعيل المكون فوراً إذا لم يكن هناك تصحيح متاح
3. مراجعة سجلات وصول المستخدم للطلبات المريبة إلى نقطة نهاية AJAX 'ninja_gdpr_ajax_actions'
4. التحقق من النصوص البرمجية الضارة المحقونة في مخرجات wp_head وكتل نمط CSS
توجيهات التصحيح:
1. التواصل مع مطور المكون بشأن توفر تصحيح أمني والجدول الزمني
2. إذا أصبح التصحيح متاحاً، اختبره في بيئة التطوير قبل نشره في الإنتاج
3. تنفيذ قواعد جدار الحماية لتطبيقات الويب (WAF) لحظر طلبات AJAX للنقاط النهائية الضعيفة
الضوابط البديلة:
1. تقييد إنشاء حسابات المستخدمين على مستوى المشترك؛ تدقيق الحسابات الموجودة
2. تنفيذ رؤوس سياسة أمان المحتوى (CSP) لمنع تنفيذ النصوص البرمجية المضمنة
3. نشر مكونات أمان WordPress (Wordfence, Sucuri) مع قواعد كشف XSS
4. تفعيل التحقق من nonce في WordPress على جميع معالجات AJAX عبر مراجعة الكود المخصص
5. تنفيذ التحقق من المدخلات والهروب من المخرجات على جميع قيم تكوين GDPR
6. مراقبة مخرجات wp_head للبحث عن علامات نمط مريبة أو حقن نصوص برمجية
قواعد الكشف:
1. مراقبة طلبات POST إلى /wp-admin/admin-ajax.php?action=ninja_gdpr_ajax_actions
2. تنبيه عند أي تعديلات على قيم gdprConfig من حسابات المشترك
3. مسح مخرجات wp_head للبحث عن علامات <style> تحتوي على JavaScript مريب أو معالجات أحداث
4. مراقبة قاعدة البيانات للبيانات المسلسلة في خيارات مكون GDPR التي تحتوي على علامات نصية
