Vulnerability from github – Published: 2026-08-21 09:32 – Updated: 2026-08-24 18:31

Details

Improper authorization for CRUD operations on Project Roles and Project Role permissions for domain admins in CloudStack.

A Domain Admin can create, update, delete, and list project roles and project role permissions for projects in any domain, not just their own. The check only confirms the caller is a Domain Admin, without verifying whether the target project belongs to their domain or subdomain. This allows a malicious Domain Admin to tamper with project roles and permissions across unrelated domains.

This issue affects Apache CloudStack: from 4.15.0.0 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.

Severity

7.2 (High)
