Technical details
The Api::V2::SshKeysController in Foreman resolves the target user via User.find(params[:user_id]) without enforcing parent-user authorization checks, creating a CWE-639 authorization bypass. An authenticated attacker with create_ssh_keys permission can POST to /api/v2/users/:user_id/ssh_keys with an arbitrary user ID to inject their public key into another account; the key is then propagated to that user's provisioned hosts, enabling SSH access.
