📄 Description (English)

The jQuery Hover Footnotes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Footnote Qualifier ('{{...}}' Syntax) in all versions up to, and including, 1.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The attribute-breakout payload (e.g., a double-quote followed by an event handler) contains no angle brackets and therefore bypasses WordPress core's wp_kses_post() filtering, which only strips disallowed HTML tags rather than sanitizing attribute contexts.

🤖 AI Executive Summary

The jQuery Hover Footnotes WordPress plugin (versions ≤1.4) contains a Stored XSS vulnerability allowing authenticated authors to inject malicious scripts via footnote qualifiers using {{...}} syntax. The vulnerability bypasses WordPress's wp_kses_post() filter through attribute-breakout payloads without angle brackets. While requiring author-level access, successful exploitation enables persistent script execution affecting all site visitors, posing significant risk to Saudi organizations using WordPress for content management.

🤖 AI Intelligence Analysis Analyzed: Jun 9, 2026 09:02
🇸🇦 Saudi Arabia Impact Assessment
Saudi organizations at highest risk include: (1) Government agencies and ministries using WordPress for public information portals and citizen services; (2) Educational institutions (universities, schools) managing course content and announcements; (3) Healthcare providers publishing medical information and patient resources; (4) Media and news organizations operating WordPress-based news sites; (5) Small-to-medium enterprises using WordPress for corporate websites. The vulnerability is particularly concerning for organizations with multiple content authors where insider threats or compromised author accounts could inject malware affecting thousands of users. ARAMCO, STC, and SAMA-regulated entities using WordPress for external communications face reputational and compliance risks.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Audit all WordPress installations using jQuery Hover Footnotes plugin ≤v1.4 across your organization
2. Disable the plugin immediately if not critical to operations
3. Review user access logs for author-level accounts to identify suspicious footnote modifications
4. Scan all published pages/posts containing {{...}} syntax for malicious payloads

PATCHING GUIDANCE:
1. Monitor plugin repository for security update (currently no patch available)
2. Contact plugin developer for timeline on security release
3. If update becomes available, test in staging environment before production deployment

COMPENSATING CONTROLS (until patch available):
1. Restrict author-level access to trusted personnel only; implement role-based access control
2. Enable WordPress security plugins (Wordfence, Sucuri) with WAF rules to detect/block XSS patterns
3. Implement Content Security Policy (CSP) headers to restrict inline script execution
4. Add custom code to sanitize footnote qualifier input: apply wp_kses_post() with additional attribute filtering
5. Enable WordPress audit logging to track all content modifications
6. Implement code review process for all footnote-containing content before publication

DETECTION RULES:
1. Monitor database for posts/pages containing {{.*['"].*on[a-z]+.*}} patterns
2. Alert on author-level user modifications to posts containing footnote syntax
3. Log all HTTP requests containing encoded XSS payloads (e.g., %27, %22, event handlers)
4. Monitor for unusual JavaScript execution in page context via browser console logs
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تدقيق جميع تثبيتات WordPress التي تستخدم مكون jQuery Hover Footnotes ≤v1.4 عبر مؤسستك
2. تعطيل المكون فوراً إذا لم يكن حرجاً للعمليات
3. مراجعة سجلات وصول المستخدمين لحسابات مستوى المؤلف لتحديد تعديلات الحواشي المريبة
4. مسح جميع الصفحات/المنشورات المنشورة التي تحتوي على بناء جملة {{...}} للبحث عن حمولات ضارة

إرشادات التصحيح:
1. مراقبة مستودع المكون للحصول على تحديث أمني (لا يوجد تصحيح متاح حالياً)
2. الاتصال بمطور المكون للحصول على الجدول الزمني لإصدار الأمان
3. إذا أصبح التحديث متاحاً، اختبره في بيئة التدريج قبل نشره في الإنتاج

الضوابط البديلة (حتى توفر التصحيح):
1. تقييد وصول مستوى المؤلف للموظفين الموثوقين فقط؛ تنفيذ التحكم في الوصول القائم على الأدوار
2. تفعيل مكونات أمان WordPress (Wordfence, Sucuri) مع قواعد WAF للكشف عن أنماط XSS
3. تنفيذ رؤوس سياسة أمان المحتوى (CSP) لتقييد تنفيذ النصوص البرمجية المضمنة
4. إضافة كود مخصص لتطهير إدخال مؤهل الحاشية: تطبيق wp_kses_post() مع تصفية السمات الإضافية
5. تفعيل تسجيل تدقيق WordPress لتتبع جميع تعديلات المحتوى
6. تنفيذ عملية مراجعة الكود لجميع المحتوى الذي يحتوي على حواشي قبل النشر

قواعد الكشف:
1. مراقبة قاعدة البيانات للبحث عن المنشورات/الصفحات التي تحتوي على أنماط {{.*['"].*on[a-z]+.*}}
2. التنبيه على تعديلات مستخدم مستوى المؤلف للمنشورات التي تحتوي على بناء جملة الحاشية
3. تسجيل جميع طلبات HTTP التي تحتوي على حمولات XSS المشفرة (مثل %27, %22, معالجات الأحداث)
4. مراقبة تنفيذ JavaScript غير العادي في سياق الصفحة عبر سجلات وحدة تحكم المتصفح
