📄 Description (English)
The WP-WebAuthn plugin for WordPress is vulnerable to Unauthenticated Stored Cross-Site Scripting via the `wwa_auth` AJAX endpoint in all versions up to, and including, 1.3.4 due to insufficient input sanitization and output escaping on user supplied attributes logged by the plugin. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses the plugin's log page, provided that the logging option is enabled in the plugin settings.
🤖 AI Executive Summary
WP-WebAuthn plugin versions up to 1.3.4 contain an unauthenticated stored XSS vulnerability in the wwa_auth AJAX endpoint that allows attackers to inject malicious scripts into plugin logs. When logging is enabled, these scripts execute for any user accessing the log page, potentially compromising administrator accounts and sensitive authentication data. This vulnerability is particularly dangerous as it requires no authentication and affects WordPress installations commonly used by Saudi organizations for web presence.

🇸🇦 Saudi Arabia Impact Assessment
Saudi organizations using WordPress for web presence, particularly in banking (SAMA-regulated fintech platforms), government agencies (NCA oversight), healthcare providers, and e-commerce sectors are at risk. The vulnerability is especially critical for organizations using WebAuthn for multi-factor authentication, as compromised administrator logs could expose authentication bypass techniques. Government entities and financial institutions relying on WordPress plugins for customer-facing applications face elevated risk of credential theft and administrative account compromise.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Disable the WP-WebAuthn plugin logging feature immediately via plugin settings if not critical to operations
2. Restrict access to plugin log pages using WordPress user roles and capabilities
3. Implement Web Application Firewall (WAF) rules to block suspicious AJAX requests to wwa_auth endpoint
4. Review plugin logs for suspicious entries containing script tags or encoded payloads
PATCHING GUIDANCE:
1. Monitor the official WP-WebAuthn GitHub repository and WordPress.org plugin page for security updates
2. Prepare to update immediately when patch version 1.3.5+ is released
3. If critical functionality depends on this plugin, consider temporary replacement with alternative WebAuthn solutions
COMPENSATING CONTROLS:
1. Implement Content Security Policy (CSP) headers to prevent inline script execution
2. Enable WordPress security plugins (Wordfence, Sucuri) with XSS detection rules
3. Restrict administrative access to log pages via IP whitelisting
4. Enable WordPress debug logging to monitor AJAX endpoint activity
5. Implement regular security audits of plugin logs for malicious content
DETECTION RULES:
1. Monitor POST requests to /wp-admin/admin-ajax.php?action=wwa_auth for unusual parameters
2. Alert on log entries containing <script>, javascript:, onerror=, onclick= patterns
3. Track access to plugin log pages by non-administrative users
4. Monitor for base64-encoded payloads in wwa_auth parameters
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. قم بتعطيل ميزة تسجيل مكون WP-WebAuthn فوراً عبر إعدادات المكون إذا لم تكن حرجة للعمليات
2. قيد الوصول إلى صفحات سجل المكون باستخدام أدوار وقدرات مستخدمي WordPress
3. طبق قواعد جدار حماية تطبيقات الويب (WAF) لحجب طلبات AJAX المريبة إلى نقطة نهاية wwa_auth
4. راجع سجلات المكون للبحث عن إدخالات مريبة تحتوي على علامات نصية أو حمولات مشفرة
إرشادات التصحيح:
1. راقب مستودع WP-WebAuthn الرسمي على GitHub وصفحة المكون على WordPress.org للتحديثات الأمنية
2. استعد للتحديث فوراً عند إصدار إصدار التصحيح 1.3.5+
3. إذا كانت الوظائف الحرجة تعتمد على هذا المكون، فكر في الاستبدال المؤقت بحلول WebAuthn بديلة
الضوابط التعويضية:
1. طبق رؤوس سياسة أمان المحتوى (CSP) لمنع تنفيذ النصوص البرمجية المضمنة
2. فعّل مكونات أمان WordPress (Wordfence, Sucuri) مع قواعد كشف XSS
3. قيد الوصول الإداري إلى صفحات السجل عبر القائمة البيضاء للعناوين
4. فعّل تسجيل تصحيح أخطاء WordPress لمراقبة نشاط نقطة نهاية AJAX
5. طبق عمليات تدقيق أمان منتظمة لسجلات المكون للبحث عن محتوى ضار
قواعد الكشف:
1. راقب طلبات POST إلى /wp-admin/admin-ajax.php?action=wwa_auth للبحث عن معاملات غير عادية
2. أصدر تنبيهات لإدخالات السجل التي تحتوي على أنماط <script>، javascript:، onerror=، onclick=
3. تتبع الوصول إلى صفحات سجل المكون من قبل المستخدمين غير الإداريين
4. راقب حمولات base64 المشفرة في معاملات wwa_auth
