CVE ID :CVE-2026-32638
Published : March 18, 2026, 8:41 p.m. | 19 minutes ago
Description :StudioCMS is a server-side-rendered, Astro native, headless content management system. Prior to 0.4.4, the REST API `getUsers` endpoint in StudioCMS uses the attacker-controlled `rank` query parameter to decide whether owner accounts should be filtered from the result set. As a result, an admin token can request `rank=owner` and receive owner account records, including IDs, usernames, display names, and email addresses, even though the adjacent `getUser` endpoint correctly blocks admins from viewing owner users. This is an authorization inconsistency inside the same user-management surface. Version 0.4.4 fixes the issue.
Severity: 0.0 | NA
