The SCIM user ingest function adopts pre-existing local accounts by username without validating scope boundaries. An attacker can rewrite or delete any account, including the superuser, using only a limited provisioning credential.","publishedAt":"2026-08-11T11:07:22.941Z","updatedAt":"2026-08-11T12:40:39.574Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"TuranSec"},"assigner":"TuranSec","products":["Authentik Security authentik"],"affected":[{"vendor":"Authentik Security","product":"authentik","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2026.5.6","versionType":"custom"}]}],"references":["https://github.com/goauthentik/authentik"],"weaknesses":["CWE-269"],"ingestedAt":"2026-10-29T20:12:58.252Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/72xxx/CVE-2026-72537.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-72537","state":"PUBLISHED","datePublished":"2026-08-11T11:07:22.941Z","dateUpdated":"2026-08-11T12:40:39.574Z","assignerShortName":"TuranSec","assignerOrgId":"309f9ea4-e3e9-4c6c-b79d-e8eb01244f2c","dateReserved":"2026-08-10T10:32:49.080Z"},"containers":{"cna":{"title":"Authentik Security authentik - Privilege Escalation","descriptions":[{"lang":"en","value":"A privilege escalation vulnerability in Authentik Security authentik through 2026.5.6 allows an attacker with a source-scoped SCIM provisioning token to take over any user account including superusers by provisioning a SCIM user that matches an existing local user by username.
