Improper authorization for CRUD operations on Project Roles and Project Role permissions for domain admins in CloudStack. (CVE-2026-66722)
A vulnerability in Apache CloudStack allows Domain Admins to improperly perform create, read, update, and delete (CRUD) operations on project roles and permissions across domains. The authorization check only verifies that the caller is a Domain Admin but does not confirm if the target project belongs to their domain or subdomain. This flaw affects versions from 4.15.0.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0. Fixed versions are 4.20.3.1 and 4.22.1.1 or later.
AI Analysis
Technical Summary
CVE-2026-66722 is an improper authorization vulnerability in Apache CloudStack that allows a Domain Admin to create, update, delete, and list project roles and permissions for projects outside their own domain. The authorization mechanism only checks if the caller is a Domain Admin but does not verify domain ownership of the target project, enabling privilege escalation across unrelated domains. This affects Apache CloudStack versions 4.15.0.0 through 4.20.3.0 and 4.21.0.0 through 4.22.1.0. The issue is resolved in versions 4.20.3.1 and 4.22.1.1 and later.
Potential Impact
A malicious Domain Admin can tamper with project roles and permissions in any domain, not limited to their own. This could lead to unauthorized access or modification of project configurations across domains, potentially compromising multi-tenant isolation within CloudStack environments.
Mitigation Recommendations
Users should upgrade Apache CloudStack to version 4.20.3.1, 4.22.1.1, or later to address this improper authorization vulnerability. No other mitigation is indicated by the vendor advisory.
