📄 Description (English)

The iVysilani Shortcode plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'width' shortcode attribute in all versions up to, and including, 3.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-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 iVysilani Shortcode WordPress plugin contains a Stored Cross-Site Scripting (XSS) vulnerability in the 'width' shortcode attribute affecting all versions up to 3.0. Authenticated users with Contributor-level access can inject malicious scripts that execute for all page visitors. While currently unpatched, the medium CVSS score (6.4) and requirement for authenticated access limit immediate risk, though the persistence of stored XSS poses significant long-term threats to WordPress-based Saudi government and corporate websites.

🤖 AI Intelligence Analysis Analyzed: May 15, 2026 17:09
🇸🇦 Saudi Arabia Impact Assessment
Saudi organizations using WordPress with the iVysilani Shortcode plugin face elevated risk, particularly: (1) Government agencies and NCA-regulated entities hosting public-facing WordPress sites for citizen services; (2) Banking and financial institutions using WordPress for customer portals or informational sites; (3) Healthcare providers (MOH, private hospitals) with WordPress-based patient information systems; (4) Telecom operators (STC, Mobily) using WordPress for service announcements; (5) Energy sector (ARAMCO, SEC) with WordPress infrastructure. The vulnerability is particularly dangerous in multi-user WordPress environments common in Saudi government and enterprise deployments where Contributor-level access is frequently granted to content teams.
🏢 Affected Saudi Sectors
Government (NCA, CITC, local authorities) Banking and Financial Services (SAMA-regulated) Healthcare (MOH, private hospitals) Energy (ARAMCO, SEC) Telecommunications (STC, Mobily, Zain) Education (universities, schools) E-commerce and Retail
⚖️ Saudi Risk Score (AI)

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Audit all WordPress installations for iVysilani Shortcode plugin presence using WP-CLI: wp plugin list | grep ivysilani
2. Identify all users with Contributor-level access and above; review their recent activity logs for suspicious shortcode modifications
3. Scan published pages/posts for 'width' shortcode attributes containing suspicious content using: wp post list --post_type=page,post --format=json | grep -i 'width'

COMPENSATING CONTROLS (until patch available):
4. Disable the plugin immediately: wp plugin deactivate ivysilani-shortcode
5. If plugin functionality is required, restrict Contributor access to trusted personnel only via role management
6. Implement Web Application Firewall (WAF) rules to detect and block XSS payloads in shortcode attributes
7. Enable WordPress security headers: X-XSS-Protection, Content-Security-Policy, X-Content-Type-Options
8. Deploy Content Security Policy (CSP) headers to prevent inline script execution

DETECTION RULES:
9. Monitor WordPress database for suspicious shortcode patterns: SELECT * FROM wp_posts WHERE post_content LIKE '%[ivysilani%width%script%' OR post_content LIKE '%[ivysilani%width%javascript%'
10. Log all post/page modifications by Contributor+ users; alert on width attribute changes
11. Implement SIEM rules to detect XSS payloads in HTTP requests targeting WordPress shortcode processing

LONG-TERM:
12. Monitor plugin repository for security updates; subscribe to WordPress security mailing lists
13. Consider alternative plugins with active security maintenance
14. Implement WordPress hardening: disable file editing, enforce strong passwords, enable two-factor authentication
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تدقيق جميع تثبيتات WordPress للتحقق من وجود مكون iVysilani Shortcode باستخدام WP-CLI: wp plugin list | grep ivysilani
2. تحديد جميع المستخدمين بمستوى المساهم وما فوقه؛ مراجعة سجلات نشاطهم الأخيرة للتعديلات المريبة على shortcode
3. مسح الصفحات/المنشورات المنشورة بحثاً عن خصائص 'width' shortcode تحتوي على محتوى مريب

الضوابط التعويضية (حتى توفر التصحيح):
4. تعطيل المكون فوراً: wp plugin deactivate ivysilani-shortcode
5. إذا كانت وظيفة المكون مطلوبة، قيّد وصول المساهم للموظفين الموثوقين فقط
6. تطبيق قواعد جدار الحماية (WAF) للكشف عن حمولات XSS ومنعها
7. تفعيل رؤوس أمان WordPress: X-XSS-Protection, Content-Security-Policy, X-Content-Type-Options
8. نشر رؤوس Content Security Policy (CSP) لمنع تنفيذ البرامج النصية المضمنة

قواعد الكشف:
9. مراقبة قاعدة بيانات WordPress للأنماط المريبة في shortcode
10. تسجيل جميع تعديلات المنشورات/الصفحات من قبل مستخدمي Contributor+؛ التنبيه عند تغييرات width
11. تطبيق قواعس SIEM للكشف عن حمولات XSS في طلبات HTTP

المدى الطويل:
12. مراقبة مستودع المكونات للتحديثات الأمنية؛ الاشتراك في قوائم أمان WordPress
13. النظر في مكونات بديلة بصيانة أمنية نشطة
14. تطبيق تقسية WordPress: تعطيل تحرير الملفات، فرض كلمات مرور قوية، تفعيل المصادقة الثنائية
