{"id":"CVE-2026-32638","state":"PUBLISHED","title":"StudioCMS REST getUsers Exposes Owner Account Records to Admin Tokens","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.","publishedAt":"2026-03-18T20:41:14.034Z","updatedAt":"2026-03-19T15:01:00.396Z","severity":{"score":2.7,"label":"Low","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["withstudiocms studiocms"],"affected":[{"vendor":"withstudiocms","product":"studiocms","versions":[{"version":"< 0.4.4","status":"affected"}]}],"references":["https://github.com/withstudiocms/studiocms/security/advisories/GHSA-xvf4-ch4q-2m24","https://github.com/withstudiocms/studiocms/commit/aebe8bcb3618bb07c6753e3f5c982c1fe6adea64","https://github.com/withstudiocms/studiocms/releases/tag/studiocms@0.4.4"],"weaknesses":["CWE-639"],"ingestedAt":"2026-10-29T20:11:40.391Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/32xxx/CVE-2026-32638.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-32638","state":"PUBLISHED","datePublished":"2026-03-18T20:41:14.034Z","dateUpdated":"2026-03-19T15:01:00.396Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-03-12T15:29:36.560Z"},"containers":{"cna":{"title":"StudioCMS REST getUsers Exposes Owner Account Records to Admin Tokens","descriptions":[{"lang":"en","value":"StudioCMS is a server-side-rendered, Astro native, headless content management system.
