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."}], "lastModified": "2026-03-19T18:40:31.577", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:studiocms:studiocms:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "EF77B4D2-70E1-4F62-AE18-5726017098A2", "versionEndExcluding": "0.4.4"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
