🔧 Remediation Steps (English)
Upgrade HACS to version 1.10.1 or later immediately. Implement network-level access controls to restrict /hacsfiles/ endpoint access. Review authentication logs for suspicious activity and reset user credentials if compromise is suspected. Disable HACS if immediate patching is not possible.
🔧 خطوات المعالجة (العربية)
قم بترقية HACS إلى الإصدار 1.10.1 أو أحدث فوراً. طبق ضوابط الوصول على مستوى الشبكة لتقييد الوصول إلى نقطة نهاية /hacsfiles/. راجع سجلات المصادقة للكشف عن النشاط المريب وأعد تعيين بيانات اعتماد المستخدم إذا اشتبهت في الاختراق. عطل HACS إذا لم يكن الإصلاح الفوري ممكناً.
