Apache CloudStack: Authorization issue with listHostTags for domain admins

Published Aug 21, 2026 · Updated Aug 24, 2026 · Assigned by apache

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.
