📄 Description (English)

WCAPF – WooCommerce Ajax Product Filter plugin is vulnerable to time-based SQL Injection via the 'post-author' parameter in all versions up to, and including, 4.2.3 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

🤖 AI Executive Summary

CVE-2026-3396 is a time-based SQL injection vulnerability in WooCommerce Ajax Product Filter plugin (versions ≤4.2.3) affecting the 'post-author' parameter. Unauthenticated attackers can exploit this to extract sensitive database information. With a CVSS score of 7.5 and no patch currently available, this poses an immediate risk to e-commerce platforms in Saudi Arabia relying on this plugin.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all WooCommerce installations using WCAPF plugin versions ≤4.2.3 across your organization
2. Disable the WCAPF plugin immediately as a temporary measure
3. Review database access logs for suspicious SQL patterns or time-based queries
4. Monitor for unauthorized data exfiltration attempts

PATCHING GUIDANCE:
1. Contact plugin vendor for security update timeline
2. Once patch is available, apply immediately after testing in non-production environment
3. Implement Web Application Firewall (WAF) rules to block SQL injection patterns targeting 'post-author' parameter

COMPENSATING CONTROLS:
1. Implement input validation and sanitization at application layer
2. Apply database-level access controls limiting query scope
3. Enable SQL query logging and anomaly detection
4. Deploy WAF rules: Block requests containing SQL keywords in 'post-author' parameter
5. Implement rate limiting on product filter endpoints

DETECTION RULES:
1. Monitor for time-based SQL injection patterns: SLEEP(), BENCHMARK(), WAITFOR in HTTP requests
2. Alert on unusual database query execution times from web application
3. Track failed authentication attempts combined with SQL error messages
4. Monitor for SELECT statements extracting user_login, user_pass, user_email from wp_users table
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع تثبيتات WooCommerce التي تستخدم إصدارات مكون WCAPF ≤4.2.3 عبر مؤسستك
2. تعطيل مكون WCAPF فوراً كإجراء مؤقت
3. مراجعة سجلات الوصول إلى قاعدة البيانات للبحث عن أنماط SQL مريبة أو استعلامات قائمة على الوقت
4. مراقبة محاولات تسرب البيانات غير المصرح بها

إرشادات التصحيح:
1. التواصل مع بائع المكون لمعرفة جدول زمني لتحديث الأمان
2. عند توفر التصحيح، قم بتطبيقه فوراً بعد الاختبار في بيئة غير الإنتاج
3. تطبيق قواعد جدار الحماية لتطبيقات الويب (WAF) لحجب أنماط حقن SQL التي تستهدف معامل 'post-author'

الضوابط البديلة:
1. تطبيق التحقق من صحة المدخلات والتطهير على مستوى التطبيق
2. تطبيق ضوابط الوصول على مستوى قاعدة البيانات لتحديد نطاق الاستعلام
3. تفعيل تسجيل استعلامات SQL والكشف عن الشذوذ
4. نشر قواعد WAF: حجب الطلبات التي تحتوي على كلمات رئيسية SQL في معامل 'post-author'
5. تطبيق تحديد معدل على نقاط نهاية مرشح المنتج

قواعد الكشف:
1. مراقبة أنماط حقن SQL القائمة على الوقت: SLEEP()، BENCHMARK()، WAITFOR في طلبات HTTP
2. تنبيه على أوقات تنفيذ استعلامات قاعدة البيانات غير العادية من تطبيق الويب
3. تتبع محاولات المصادقة الفاشلة مع رسائل خطأ SQL
4. مراقبة استعلامات SELECT التي تستخرج user_login و user_pass و user_email من جدول wp_users
