📄 Description (English)
The Splide Carousel Block plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'url' Block Attribute in all versions up to, and including, 1.7.1 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. The injected payload must be published before it executes for site visitors, which requires an editor or administrator to approve and publish the contributor's post.
🤖 AI Executive Summary
The Splide Carousel Block WordPress plugin (versions ≤1.7.1) contains a Stored XSS vulnerability in the 'url' block attribute that allows authenticated contributors to inject malicious scripts. While requiring editor/admin approval for publication, successful exploitation enables persistent XSS attacks affecting all site visitors. This vulnerability poses moderate risk to Saudi organizations using WordPress with this plugin, particularly those with multiple content contributors.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Audit all WordPress installations using Splide Carousel Block plugin and identify version numbers
2. Review user access logs for contributor-level and above accounts, focusing on last 90 days
3. Inspect all published posts/pages containing carousel blocks for suspicious URLs or script patterns
4. Disable the Splide Carousel Block plugin immediately if not critical to operations
PATCHING GUIDANCE:
1. Monitor plugin repository for security updates (currently no patch available)
2. Contact plugin developer for patch timeline and security advisory
3. Consider switching to alternative carousel plugins with better security track records
COMPENSATING CONTROLS (until patch available):
1. Restrict contributor role permissions - limit to trusted staff only
2. Implement mandatory content review workflow requiring admin approval before publication
3. Deploy Web Application Firewall (WAF) rules to detect/block XSS payloads in carousel URLs
4. Enable WordPress security plugins (Wordfence, Sucuri) with XSS detection
5. Implement Content Security Policy (CSP) headers to restrict script execution
DETECTION RULES:
1. Monitor database for suspicious JavaScript patterns in post_content containing 'splide' class
2. Alert on contributor posts containing <script>, javascript:, onerror=, onload= in URL parameters
3. Log all post modifications by contributor-level users for review
4. Monitor for unusual external URLs in carousel block attributes
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تدقيق جميع تثبيتات WordPress التي تستخدم مكون Splide Carousel Block وتحديد أرقام الإصدارات
2. مراجعة سجلات الوصول للمستخدمين على مستوى المساهم وما فوقه، مع التركيز على آخر 90 يوماً
3. فحص جميع المنشورات/الصفحات المنشورة التي تحتوي على كتل الكاروسيل للعثور على عناوين URL أو أنماط برامج نصية مريبة
4. تعطيل مكون Splide Carousel Block فوراً إذا لم يكن حرجاً للعمليات
إرشادات التصحيح:
1. مراقبة مستودع المكون للتحديثات الأمنية (لا يوجد تصحيح متاح حالياً)
2. الاتصال بمطور المكون للحصول على جدول زمني للتصحيح والمشورة الأمنية
3. النظر في التبديل إلى مكونات كاروسيل بديلة بسجلات أمان أفضل
الضوابط التعويضية (حتى توفر التصحيح):
1. تقييد أذونات دور المساهم - حصرها على الموظفين الموثوقين فقط
2. تنفيذ سير عمل مراجعة محتوى إلزامي يتطلب موافقة المسؤول قبل النشر
3. نشر قواعد جدار الحماية لتطبيقات الويب (WAF) للكشف عن حمولات XSS وحجبها
4. تفعيل مكونات أمان WordPress (Wordfence, Sucuri) مع كشف XSS
5. تنفيذ رؤوس سياسة أمان المحتوى (CSP) لتقييد تنفيذ البرامج النصية
قواعد الكشف:
1. مراقبة قاعدة البيانات للعثور على أنماط JavaScript مريبة في post_content التي تحتوي على فئة 'splide'
2. التنبيه على منشورات المساهمين التي تحتوي على <script>، javascript:، onerror=، onload= في معاملات URL
3. تسجيل جميع تعديلات المنشورات من قبل مستخدمي مستوى المساهم للمراجعة
4. مراقبة عناوين URL الخارجية غير العادية في خصائص كتلة الكاروسيل
