Foreman: foreman: cross-tenant private ssh key disclosure via taxonomy scoping bypass
Overview
Description
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.

Solution
Restrict key pair access based on tenant and organization.
- Review and restrict user permissions for viewing key pairs.
- Implement strict access control for SSH key management.
- Ensure taxonomy scoping is enforced for all key pair access.
- Update the software to the latest secure version.
