The issue occurs when an administrator enforces a stronger authentication flow, such as mandatory two-factor authentication (2FA) setup, through a client policy. A user can bypass this requirement by manually visiting a specific session restart web link during the login process. This action clears the internal markers that track the required security steps, allowing the user to log in with only a password and gain access without completing the mandated 2FA setup.","severity":{"version":"3.1","score":3.1,"vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:N","level":"low","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-11","score":0.0039,"percentile":0.33523,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-862"],"published":"2026-09-21T06:45:34Z","modified":"2026-11-07T11:52:17Z","products":[{"vendor":"red hat","product":"red hat build of keycloak 26.6.8"},{"vendor":"red hat","product":"red hat single sign-on 7"}],"references":[{"url":"https://access.redhat.com/errata/RHSA-2026:95761","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2026:95762","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/security/cve/CVE-2026-94218","tags":["vdb-entry","x_refsource_REDHAT"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2537314","tags":["issue-tracking","x_refsource_REDHAT"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-94218"},{"url":"https://github.com/advisories/GHSA-rm49-qjx7-5qm5"}],"sources":{"cve":[{"id":"CVE-2026-94218","title":"Keycloak-services: keycloak-services: 2fa setup enforcement bypass via authentication session restart endpoint","description":"A flaw was found in the authentication session management of Keycloak, an identity and access management solution.
