Apache CloudStack 4.20 ACL Bypass via listTemplates/listIsos CVE-2025-30675
CVE-2025-30675 Published on June 11, 2025

Apache CloudStack: Unauthorised template/ISO list access to the domain/resource admins
In Apache CloudStack, a flaw in access control affects the listTemplates and listIsos APIs. A malicious Domain Admin or Resource Admin can exploit this issue by intentionally specifying the 'domainid' parameter along with the 'filter=self' or 'filter=selfexecutable' values. This allows the attacker to gain unauthorized visibility into templates and ISOs under the ROOT domain. A malicious admin can enumerate and extract metadata of templates and ISOs that belong to unrelated domains, violating isolation boundaries and potentially exposing sensitive or internal configuration details.  This vulnerability has been fixed by ensuring the domain resolution strictly adheres to the caller's scope rather than defaulting to the ROOT domain. Affected users are recommended to upgrade to Apache CloudStack 4.19.3.0 or 4.20.1.0.
