A flaw was found in Katello's of Red Hat Satellite. A content upload functionality where insufficient authorization checks in the ContentUploadsController allowed users with the edit_products permission to query content information for repositories outside the products they were authorized to manage. An authenticated attacker could exploit this issue to determine whether specific content exists within repositories that should otherwise be inaccessible. This issue does not allow unauthorized modification, import, or publication of content.

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:50221 advisory.

    Red Hat Satellite is a system management solution that allows organizations     to configure and maintain their systems without the necessity to provide     public Internet access to their servers or other client systems. It     performs provisioning and configuration management of predefined standard     operating environments.
