📄 Description (English)

A flaw was found in KubeVirt's Role-Based Access Control (RBAC) evaluation logic. The authorization mechanism improperly truncates subresource names, leading to incorrect permission evaluations. This allows authenticated users with specific custom roles to gain unauthorized access to subresources, potentially disclosing sensitive information or performing actions they are not permitted to do. Additionally, legitimate users may be denied access to resources.

🤖 AI Executive Summary

KubeVirt's RBAC evaluation logic improperly truncates subresource names, allowing authenticated users with custom roles to gain unauthorized access to subresources and sensitive information. This flaw affects both unauthorized access and denial of legitimate user access to resources.

📄 Description (Arabic)

يحتوي KubeVirt على خلل في آلية تقييم التحكم في الوصول القائم على الأدوار حيث يتم قطع أسماء الموارد الفرعية بشكل غير صحيح. يسمح هذا للمستخدمين المصرحين بأدوار مخصصة بتجاوز التفويض والوصول إلى موارد فرعية غير مصرح لهم بها. قد يؤدي الخلل أيضاً إلى حرمان المستخدمين الشرعيين من الوصول إلى الموارد.

🤖 ملخص تنفيذي (AI)
