What is CVE-2026-5142?

A security flaw in Foreman allows authenticated users with the 'view_keypairs' permission to bypass taxonomy scoping. This weakness enables users to directly query key pair IDs, facilitating the unauthorized download of private SSH keys from other organizations in a multi-tenant deployment. Such access can lead to significant exposure of sensitive data and compromise overall system integrity.
