{"id":"BIT-authentik-2026-94606","summary":"authentik: MFA Bypass via State Confusion / Parameter Injection in AuthenticatorEmailStage","details":"authentik is an open-source identity provider. Prior to 2026.2.7, 2026.5.7, and 2026.8.2, authentik email authenticator enrollment during an authentication or enrollment flow accepts a recipient address supplied in the setup request instead of using the address already established by the flow. An actor who knows a target user's password can substitute an attacker-controlled address, receive the one-time code, and finish enrolling the factor as the target. The target must not have enrolled the email factor already. Successful enrollment gives the actor a session as the target and access to single sign-on applications behind the account. Other authenticator types are not affected. This issue is fixed in versions 2026.2.7, 2026.5.7, and 2026.8.2.","aliases":["CVE-2026-94606","GHSA-qgqp-xh8r-v73r"],"modified":"2026-10-01T10:11:06.489220472Z","published":"2026-10-01T09:23:05.728Z","database_specific":{"cpes":["cpe:2.3:a:goauthentik:authentik:*:*:*:*:*:*:*:*"],"severity":"High"},"references":[{"type":"WEB","url":"https://docs.goauthentik.io/releases/2026.2#fixed-in-202627"},{"type":"WEB","url":"https://docs.goauthentik.io/releases/2026.5#fixed-in-202657"},{"type":"WEB","url":"https://docs.goauthentik.io/releases/2026.8#fixed-in-202682"},{"type":"WEB","url":"https://github.com/goauthentik/authentik/commit/01d4349f2aaa9beda532f92e2a251a17fefee9b3"},{"type":"WEB","url":"https://github.com/goauthentik/authentik/commit/1fcf9868133e5d05e266edbc1f6f3ee972baa3f9"},{"type":"WEB","url":"https://github.com/goauthentik/authentik/commit/c10ae83ebf8c61de2f1922edf1fab504d9f3b06f"},{"type":"WEB","url":"https://github.com/goauthentik/authentik/commit/ec41732339726fba477182c0906a8d930b145beb"},{"type":"WEB","url":"https://github.com/goauthentik/authentik/pull/25958"},{"type":"WEB","url":"https://github.com/goauthentik/authentik/pull/25963"},{"type":"WEB","url":"https://github.com/goauthentik/authentik/pull/25968"},{"type":"WEB","url":"https://github.com/goauthentik/authentik/pull/25973"},{"type":"WEB","url":"https://github.com/goauthentik/authentik/releases/tag/version/2026.2.7"},{"type":"WEB","url":"https://github.com/goauthentik/authentik/releases/tag/version/2026.5.7"},{"type":"WEB","url":"https://github.com/goauthentik/authentik/releases/tag/version/2026.8.2"},{"type":"WEB","url":"https://github.com/goauthentik/authentik/security/advisories/GHSA-qgqp-xh8r-v73r"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-94606"}],"affected":[{"package":{"name":"authentik","ecosystem":"Bitnami","purl":"pkg:bitnami/authentik"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.2.7"},{"introduced":"2026.5.0"},{"fixed":"2026.5.7"},{"introduced":"2026.8.0"},{"fixed":"2026.8.2"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/authentik/BIT-authentik-2026-94606.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:L"}]}],"schema_version":"1.9.0"}
