CVE-2026-66722: CWE-285 Improper Authorization in Apache Software Foundation Apache CloudStack
CVE-2026-66722 is an improper authorization vulnerability in Apache CloudStack affecting domain admins. It allows a domain admin to create, update, delete, and list project roles and permissions across any domain, not limited to their own. This occurs because the authorization check only verifies the caller is a domain admin without confirming domain ownership of the target project. The issue affects Apache CloudStack versions from 4.15.0.0 through 4.20.3.0 and 4.21.0.0 through 4.22.1.0. Upgrading to versions 4.20.3.1 or 4.22.1.1 or later resolves the vulnerability.
AI Analysis
Technical Summary
CVE-2026-66722 describes an improper authorization vulnerability in Apache CloudStack where Domain Admins can perform create, update, delete, and list operations on project roles and permissions for projects outside their own domain. The authorization check only verifies the caller's Domain Admin status but does not confirm whether the targeted project belongs to the caller's domain or subdomain. This flaw enables a malicious Domain Admin to tamper with project roles and permissions across unrelated domains. The vulnerability affects Apache CloudStack versions from 4.15.0.0 through 4.20.3.0 and 4.21.0.0 through 4.22.1.0. Upgrading to versions 4.20.3.1 or 4.22.1.1 or later resolves the issue.
Potential Impact
A malicious Domain Admin can modify project roles and permissions in domains they do not own or manage, potentially leading to unauthorized privilege escalation or disruption of project access controls across unrelated domains within the CloudStack environment.
Mitigation Recommendations
Users should upgrade Apache CloudStack to version 4.20.3.1, 4.22.1.1, or later to remediate this improper authorization vulnerability. No other mitigation or temporary workaround is indicated in the available data.
