📄 الوصف (الإنجليزية)
The Japanized for WooCommerce plugin for WordPress is vulnerable to Improper Authentication in versions up to, and including, 2.8.4. This is due to a flawed permission check in the `paidy_webhook_permission_check` function that unconditionally returns `true` when the webhook signature header is omitted. This makes it possible for unauthenticated attackers to bypass payment verification and fraudulently mark orders as "Processing" or "Completed" without actual payment via a crafted POST request to the Paidy webhook endpoint.
🤖 ملخص AI
The Japanized for WooCommerce plugin contains an authentication bypass vulnerability (CVE-2026-1305) allowing unauthenticated attackers to manipulate order statuses without payment verification. Attackers can fraudulently mark orders as 'Processing' or 'Completed' by omitting webhook signature headers, directly impacting e-commerce payment integrity. While CVSS is medium (5.3), the business impact is significant for Saudi retailers and payment processors relying on this plugin.

🇸🇦 التأثير على المملكة العربية السعودية
High impact for Saudi e-commerce sector, particularly small and medium retailers using WooCommerce with Paidy payment integration. Banking sector (SAMA-regulated payment processors) faces fraud risk if processing Paidy transactions. Telecom and retail sectors using WooCommerce for online sales are vulnerable. Government procurement platforms using WooCommerce may face order manipulation risks. The vulnerability enables direct financial fraud without compensating controls in place.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Disable the Japanized for WooCommerce plugin immediately if Paidy payment processing is not essential
2. If plugin is required, restrict webhook access via Web Application Firewall (WAF) rules to known Paidy IP ranges only
3. Implement IP whitelisting at the server level for the /paidy-webhook endpoint
4. Monitor order status changes for suspicious patterns (orders marked complete without payment records)
PATCHING GUIDANCE:
1. Contact plugin vendor for security patch timeline
2. Upgrade to version 2.8.5 or later once available
3. Implement temporary signature validation in custom code if patch unavailable
COMPENSATING CONTROLS:
1. Add server-side webhook signature validation using HMAC-SHA256 before processing
2. Implement order status change logging and alerting for unauthorized transitions
3. Require manual payment verification before order fulfillment
4. Deploy rate limiting on webhook endpoint to prevent automated attacks
5. Use Web Application Firewall rules to block requests without valid signature headers
DETECTION RULES:
1. Alert on POST requests to /paidy-webhook without 'X-Paidy-Signature' header
2. Monitor for order status changes to 'Processing' or 'Completed' without corresponding payment gateway records
3. Track webhook requests from non-Paidy IP addresses
4. Log all failed payment attempts followed by successful order completion
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. قم بتعطيل مكون Japanized for WooCommerce فوراً إذا لم تكن معالجة دفع Paidy ضرورية
2. إذا كان المكون مطلوباً، قيد وصول webhook عبر جدار حماية تطبيقات الويب (WAF) إلى نطاقات عناوين IP المعروفة من Paidy فقط
3. قم بتنفيذ القائمة البيضاء للعناوين على مستوى الخادم لنقطة نهاية /paidy-webhook
4. راقب تغييرات حالة الطلب بحثاً عن أنماط مريبة
إرشادات التصحيح:
1. اتصل بمورد المكون للحصول على جدول زمني لتصحيح الأمان
2. قم بالترقية إلى الإصدار 2.8.5 أو أحدث عند توفره
3. قم بتنفيذ التحقق من التوقيع المؤقت في الكود المخصص إذا لم يكن التصحيح متاحاً
الضوابط البديلة:
1. أضف التحقق من توقيع webhook على جانب الخادم باستخدام HMAC-SHA256 قبل المعالجة
2. قم بتنفيذ تسجيل وتنبيهات تغيير حالة الطلب للانتقالات غير المصرح بها
3. اطلب التحقق اليدوي من الدفع قبل تنفيذ الطلب
4. قم بنشر تحديد معدل على نقطة نهاية webhook لمنع الهجمات الآلية
5. استخدم قواعد جدار حماية تطبيقات الويب لحظر الطلبات بدون رؤوس توقيع صحيحة
