{"id":"CVE-2026-94609","published":"2026-09-24T17:17:17.230","lastModified":"2026-09-28T16:17:18.200","description":"authentik is an open-source identity provider. Prior to 2026.2.7, 2026.5.7, and 2026.8.2, an account with delegated permission to manage a group, group membership, or a user can grant superuser status to an account or assign an existing role to a group without holding the permissions that gate those privileges. Group hierarchy checks do not consistently account for superuser status inherited from ancestor groups, and role assignment to a group lacks the required authorization check. Only deployments that delegate these management capabilities to accounts that are not full administrators are affected. This issue is fixed in versions 2026.2.7, 2026.5.7, and 2026.8.2.","cvssScore":8.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-269","CWE-863"],"vendors":[],"products":[],"references":[{"url":"https://docs.goauthentik.io/releases/2026.2#fixed-in-202627","tags":[]},{"url":"https://docs.goauthentik.io/releases/2026.5#fixed-in-202657","tags":[]},{"url":"https://docs.goauthentik.io/releases/2026.8#fixed-in-202682","tags":[]},{"url":"https://github.com/goauthentik/authentik/commit/5f95b86f6f70c3bd8c625a4f9ae474e235f84030","tags":[]},{"url":"https://github.com/goauthentik/authentik/commit/67317f66f1b7eb16f2a26bf550dfd73699d49d87","tags":[]},{"url":"https://github.com/goauthentik/authentik/commit/67e470dde8c81a40ee27ec6e178462368c561a60","tags":[]},{"url":"https://github.com/goauthentik/authentik/commit/898e4e4fa070642a3541a376af0de64fe3ffeb67","tags":[]},{"url":"https://github.com/goauthentik/authentik/pull/25956","tags":[]},{"url":"https://github.com/goauthentik/authentik/pull/25961","tags":[]},{"url":"https://github.com/goauthentik/authentik/pull/25966","tags":[]},{"url":"https://github.com/goauthentik/authentik/pull/25971","tags":[]},{"url":"https://github.com/goauthentik/authentik/releases/tag/version/2026.2.7","tags":[]},{"url":"https://github.com/goauthentik/authentik/releases/tag/version/2026.5.7","tags":[]},{"url":"https://github.com/goauthentik/authentik/releases/tag/version/2026.8.2","tags":[]},{"url":"https://github.com/goauthentik/authentik/security/advisories/GHSA-h6c5-mpvq-j4jc","tags":[]}],"exploitRefs":[{"url":"https://github.com/goauthentik/authentik/commit/5f95b86f6f70c3bd8c625a4f9ae474e235f84030","tags":[]},{"url":"https://github.com/goauthentik/authentik/commit/67317f66f1b7eb16f2a26bf550dfd73699d49d87","tags":[]},{"url":"https://github.com/goauthentik/authentik/commit/67e470dde8c81a40ee27ec6e178462368c561a60","tags":[]},{"url":"https://github.com/goauthentik/authentik/commit/898e4e4fa070642a3541a376af0de64fe3ffeb67","tags":[]},{"url":"https://github.com/goauthentik/authentik/pull/25956","tags":[]},{"url":"https://github.com/goauthentik/authentik/pull/25961","tags":[]},{"url":"https://github.com/goauthentik/authentik/pull/25966","tags":[]},{"url":"https://github.com/goauthentik/authentik/pull/25971","tags":[]},{"url":"https://github.com/goauthentik/authentik/releases/tag/version/2026.2.7","tags":[]},{"url":"https://github.com/goauthentik/authentik/releases/tag/version/2026.5.7","tags":[]},{"url":"https://github.com/goauthentik/authentik/releases/tag/version/2026.8.2","tags":[]},{"url":"https://github.com/goauthentik/authentik/security/advisories/GHSA-h6c5-mpvq-j4jc","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw allows an account with delegated permissions to grant superuser status or assign roles, bypassing necessary authorization checks, leading to unauthorized administrative access.","exploitability":"Exploitation is moderately hard as it requires an account with delegated permissions and knowledge of the affected group hierarchy, but preconditions are necessary to identify vulnerable deployments.","blast_radius":"If exploited, this could result in full administrative control being granted to unauthorized accounts, leading to potential data breaches or system compromise.","remediation":"Upgrade to authentik version 2026.2.7, 2026.5.7, or 2026.8.2.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["auth-bypass","web","identity","privilege-escalation"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-09-29T09:01:33.079Z"}}
