📄 Description (English)
The Gallagher Website Design plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's login_link shortcode in all versions up to, and including, 2.6.4 due to insufficient input sanitization and output escaping on the 'prefix' attribute. 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 Gallagher Website Design WordPress plugin (versions ≤2.6.4) contains a Stored Cross-Site Scripting (XSS) vulnerability in the login_link shortcode's 'prefix' attribute. Authenticated attackers with Contributor-level access can inject malicious scripts that execute for all page visitors. While no patch is currently available and exploit code is not public, the vulnerability poses a moderate risk to WordPress sites using this plugin, particularly those with multiple content contributors.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Audit all pages/posts using the login_link shortcode for suspicious 'prefix' attribute values
2. Review user access logs for Contributor+ level accounts created or modified in recent months
3. Disable the Gallagher Website Design plugin if not actively required
PATCHING GUIDANCE:
1. Contact Gallagher Website Design plugin developers for patch timeline
2. Monitor WordPress plugin repository for security updates
3. Subscribe to WordPress security mailing lists for notification
COMPENSATING CONTROLS (until patch available):
1. Restrict Contributor-level access to trusted users only; audit existing permissions
2. Implement Web Application Firewall (WAF) rules to detect/block XSS payloads in shortcode attributes
3. Enable WordPress security plugins (Wordfence, Sucuri) with XSS detection
4. Implement Content Security Policy (CSP) headers to restrict inline script execution
5. Use WordPress user role management to limit shortcode usage to Editors/Administrators only
DETECTION RULES:
1. Monitor database for login_link shortcodes containing script tags, event handlers (onclick, onerror), or encoded payloads
2. Log all post/page modifications by Contributor+ accounts
3. Alert on any changes to shortcode attributes containing special characters: <, >, ", ', javascript:, onerror, onload
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تدقيق جميع الصفحات والمنشورات التي تستخدم اختصار login_link للتحقق من قيم سمة 'prefix' المريبة
2. مراجعة سجلات الوصول للمستخدمين بمستوى المساهم فما فوق المُنشأة أو المعدلة في الأشهر الأخيرة
3. تعطيل مكون Gallagher Website Design إذا لم يكن مطلوباً بشكل نشط
إرشادات التصحيح:
1. التواصل مع مطوري مكون Gallagher للحصول على جدول زمني للتصحيح
2. مراقبة مستودع مكونات WordPress للتحديثات الأمنية
3. الاشتراك في قوائم البريد الأمنية لـ WordPress للحصول على إشعارات
الضوابط البديلة (حتى توفر التصحيح):
1. تقييد وصول المساهمين للمستخدمين الموثوقين فقط؛ تدقيق الأذونات الحالية
2. تطبيق قواعد جدار حماية تطبيقات الويب (WAF) للكشف عن حمولات XSS وحجبها
3. تفعيل مكونات أمان WordPress (Wordfence, Sucuri) مع كشف XSS
4. تطبيق رؤوس Content Security Policy (CSP) لتقييد تنفيذ النصوص البرمجية المضمنة
5. استخدام إدارة أدوار المستخدمين في WordPress لتقييد استخدام الاختصارات على المحررين/المسؤولين فقط
قواعد الكشف:
1. مراقبة قاعدة البيانات للاختصارات التي تحتوي على علامات script أو معالجات أحداث أو حمولات مشفرة
2. تسجيل جميع تعديلات المنشورات/الصفحات من قبل حسابات المساهم+
3. التنبيه على أي تغييرات في سمات الاختصار تحتوي على أحرف خاصة: <, >, ", ', javascript:, onerror, onload
