Apache CloudStack versions 4.12.0.0 through 4.22.1.0 are vulnerable due to a missing authorization check in the listHostTags API, allowing domain admins to access host tags across all domains rather than being restricted to their own. This could lead to unauthorized visibility of host configurations, posing a significant security risk. Organizations using affected versions should prioritize upgrading to 4.20.3.1 or 4.22.1.1 or later to mitigate this vulnerability.

Original NVD Description

Missing authorization issue for domain admins in CloudStack's host tags listing functionality. Domain Admins, by default, have permission to call the listHostTags API, but the API returns host tags for every host in the environment without domain scoping. It should instead be restricted to only the hosts dedicated to that admin's domain. This issue affects Apache CloudStack: from 4.12.0.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0. Users are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.
