{"id":"CVE-2026-94606","published":"2026-09-24T17:17:17.063","lastModified":"2026-09-25T13:22:04.673","description":"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.","cvssScore":8.9,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:L","cwes":["CWE-287","CWE-807"],"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/01d4349f2aaa9beda532f92e2a251a17fefee9b3","tags":[]},{"url":"https://github.com/goauthentik/authentik/commit/1fcf9868133e5d05e266edbc1f6f3ee972baa3f9","tags":[]},{"url":"https://github.com/goauthentik/authentik/commit/c10ae83ebf8c61de2f1922edf1fab504d9f3b06f","tags":[]},{"url":"https://github.com/goauthentik/authentik/commit/ec41732339726fba477182c0906a8d930b145beb","tags":[]},{"url":"https://github.com/goauthentik/authentik/pull/25958","tags":[]},{"url":"https://github.com/goauthentik/authentik/pull/25963","tags":[]},{"url":"https://github.com/goauthentik/authentik/pull/25968","tags":[]},{"url":"https://github.com/goauthentik/authentik/pull/25973","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-qgqp-xh8r-v73r","tags":[]}],"exploitRefs":[{"url":"https://github.com/goauthentik/authentik/commit/01d4349f2aaa9beda532f92e2a251a17fefee9b3","tags":[]},{"url":"https://github.com/goauthentik/authentik/commit/1fcf9868133e5d05e266edbc1f6f3ee972baa3f9","tags":[]},{"url":"https://github.com/goauthentik/authentik/commit/c10ae83ebf8c61de2f1922edf1fab504d9f3b06f","tags":[]},{"url":"https://github.com/goauthentik/authentik/commit/ec41732339726fba477182c0906a8d930b145beb","tags":[]},{"url":"https://github.com/goauthentik/authentik/pull/25958","tags":[]},{"url":"https://github.com/goauthentik/authentik/pull/25963","tags":[]},{"url":"https://github.com/goauthentik/authentik/pull/25968","tags":[]},{"url":"https://github.com/goauthentik/authentik/pull/25973","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-qgqp-xh8r-v73r","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw allows an attacker to substitute an email address during the enrollment process, potentially gaining access to the user's account.","exploitability":"Exploitation requires knowledge of the target user's password and the absence of prior email factor enrollment.
