Summary

A flaw was found in foreman. Authenticated users with 'view_keypairs' permission can bypass taxonomy scoping, allowing them to download private SSH (Secure Shell) keys from other organizations by directly querying key pair IDs. This vulnerability leads to cross-tenant data exposure in multi-tenant deployments, potentially compromising sensitive information.
