📄 Description (English)
WordPress Popup Builder 3.49 contains a persistent cross-site scripting vulnerability that allows authenticated attackers to inject malicious scripts by breaking out of option tags in the post_title parameter. Attackers can submit crafted POST requests to the post.php endpoint with script payloads in the post_title field that execute when pages or posts display popup selections.
🤖 AI Executive Summary
WordPress Popup Builder 3.49 contains a persistent XSS vulnerability allowing authenticated attackers to inject malicious scripts via the post_title parameter. The vulnerability enables script execution when popup selections are displayed, potentially compromising website visitors and data. While no public exploit exists, the lack of available patches presents ongoing risk to Saudi organizations using this plugin.

🔧 Remediation Steps (English)
Immediate Actions:
1. Audit all WordPress installations for Popup Builder 3.49 usage across your organization
2. Disable the Popup Builder plugin immediately if version 3.49 is detected
3. Review post_title fields in database for suspicious script content using: SELECT ID, post_title FROM wp_posts WHERE post_title LIKE '%<script%' OR post_title LIKE '%javascript:%'
4. Check WordPress admin audit logs for unauthorized post modifications
Patching Guidance:
1. Update to Popup Builder version 3.50 or later if available from official repository
2. If no update available, uninstall the plugin and migrate to alternative popup solutions (e.g., Elementor, Divi, MonsterInsights)
3. Implement Web Application Firewall (WAF) rules to block script injection in POST requests to post.php
Compensating Controls:
1. Restrict post.php access to specific IP ranges of authorized administrators
2. Implement Content Security Policy (CSP) headers: Content-Security-Policy: script-src 'self'
3. Enable WordPress security plugins (Wordfence, Sucuri) with XSS detection
4. Enforce strong authentication (2FA) for all WordPress admin accounts
5. Regular security scanning using WPScan or similar tools
Detection Rules:
1. Monitor POST requests to /wp-admin/post.php with post_title parameters containing: <script, javascript:, onerror=, onload=
2. Alert on database modifications to wp_posts.post_title containing script tags
3. Monitor for unusual admin user activity during off-hours
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تدقيق جميع تثبيتات WordPress للتحقق من استخدام Popup Builder 3.49 في جميع أنحاء المنظمة
2. تعطيل مكون Popup Builder فوراً إذا تم اكتشاف الإصدار 3.49
3. مراجعة حقول post_title في قاعدة البيانات للبحث عن محتوى برامج نصية مريبة
4. فحص سجلات تدقيق WordPress للتحقق من التعديلات غير المصرح بها على المنشورات
إرشادات التصحيح:
1. التحديث إلى إصدار Popup Builder 3.50 أو أحدث إن توفر من المستودع الرسمي
2. إذا لم يكن هناك تحديث متاح، قم بإلغاء تثبيت المكون والهجرة إلى حلول منبثقة بديلة
3. تطبيق قواعد جدار حماية تطبيقات الويب (WAF) لحظر حقن البرامج النصية
الضوابط البديلة:
1. تقييد الوصول إلى post.php لنطاقات IP محددة للمسؤولين المصرح لهم
2. تطبيق رؤوس سياسة أمان المحتوى (CSP)
3. تفعيل مكونات أمان WordPress (Wordfence, Sucuri) مع كشف XSS
4. فرض المصادقة القوية (2FA) لجميع حسابات مسؤول WordPress
5. المسح الأمني المنتظم باستخدام WPScan أو أدوات مماثلة
