CVE-2026-111683
Description
A flaw was found in Ralph. Due to missing authorization checks in certain Application Programming Interface (API) endpoints, an authenticated attacker with staff privileges can bypass rack permission controls. This flaw allows an attacker to disclose sensitive asset information, such as hostnames, serial numbers, and management Internet Protocol (IP) addresses, as well as create, modify, or relocate datacenter racks without appropriate permissions.
Statement
This vulnerability is rated as Moderate impact because successful exploitation requires authenticated staff-level access, limiting the scope of unauthorized asset metadata disclosure and rack manipulation to trusted internal accounts. Allegro Ralph is not packaged or distributed within Red Hat enterprise products, and this flaw does not affect Red Hat supported software.
