A flaw was found in libxml2. This vulnerability occurs when the library processes a specially crafted XML Schema Definition (XSD) validated document that includes an internal entity reference. An attacker could exploit this by providing a malicious document, leading to a type confusion error that causes the application to crash. This results in a denial of service (DoS), making the affected system or application unavailable.
CVE-2026-6732 is a type confusion vulnerability in libxml2 that occurs when processing specially crafted XSD-validated XML documents with internal entity references, causing denial of service through application crashes. Organizations using libxml2 for XML processing should update to patched versions to prevent service disruptions.
تحتوي هذه الثغرة على خلل في معالجة مستندات XML المصممة خصيصاً التي تحتوي على تعريفات مخطط XML (XSD) وإشارات كيانات داخلية. يمكن للمهاجمين استغلال هذا الخلل لإرسال مستندات ضارة تسبب التباساً في النوع وتؤدي إلى انهيار التطبيق.

Organizations using libxml2 for XML processing should update to patched versions to prevent service disruptions.
Update libxml2 to the latest patched version immediately. Implement input validation and sanitization for XML documents before processing. Deploy Web Application Firewalls (WAF) to filter malicious XML payloads. Monitor system logs for unexpected crashes related to XML processing. Restrict XML processing capabilities to trusted sources only.
قم بتحديث libxml2 إلى أحدث إصدار معدل فوراً. قم بتنفيذ التحقق من صحة المدخلات وتنظيف مستندات XML قبل المعالجة. نشر جدران حماية تطبيقات الويب لتصفية حمولات XML الضارة. مراقبة سجلات النظام للأعطال غير المتوقعة المتعلقة بمعالجة XML. تقييد قدرات معالجة XML للمصادر الموثوقة فقط.
