CVE-2026-66722: CWE-285 Improper Authorization in Apache Software Foundation Apache CloudStack
Description
CVE-2026-66722 is an improper authorization vulnerability in Apache CloudStack affecting versions 4.15.0.0 through 4.20.3.0 and 4.21.0.0 through 4.22.1.0. It allows a Domain Admin to perform create, update, delete, and list operations on project roles and permissions across any domain, not limited to their own. This occurs because the authorization check only verifies the caller's Domain Admin status without confirming domain ownership of the target project. The issue is fixed in versions 4.20.3.1 and 4.22.1.1 or later.

Technical Analysis
The vulnerability in Apache CloudStack (CVE-2026-66722) involves improper authorization (CWE-285) for CRUD operations on project roles and permissions. Domain Admins can manipulate project roles and permissions in domains outside their own because the system only checks if the caller is a Domain Admin, not whether the project belongs to their domain or subdomain. This flaw affects Apache CloudStack versions from 4.15.0.0 through 4.20.3.0 and 4.21.0.0 through 4.22.1.0. The vendor has released fixed versions 4.20.3.1 and 4.22.1.1 to address this issue.
Potential Impact
An attacker with Domain Admin privileges can escalate their control by modifying project roles and permissions in unrelated domains, potentially leading to unauthorized access and privilege escalation across domains. The vulnerability impacts confidentiality, integrity, and availability as indicated by the CVSS vector (C:H/I:H/A:H).
Mitigation Recommendations
Users should upgrade Apache CloudStack to version 4.20.3.1 or 4.22.1.1 or later, where this improper authorization issue is fixed. No other mitigations are specified. Patch status is confirmed by the vendor advisory.
