When a disabled Security Assertion Markup Language (SAML) client is configured as an Identity Provider (IdP)-initiated broker landing target, it can still complete the login process and establish a Single Sign-On (SSO) session. This allows a remote attacker to gain unauthorized access to other enabled clients without re-authentication, effectively bypassing security restrictions.","published":"2026-03-05T18:28:36.337Z","modified":"2026-08-26T01:11:25.251462404Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.keycloak:keycloak-broker-saml","fixedVersion":null}],"fix":null,"references":[{"type":"WEB","url":"https://access.redhat.com/downloads/content/package-browser/"},{"type":"WEB","url":"https://catalog.redhat.com/software/containers/"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-3047.json"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:3925"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:3926"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:3947"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:3948"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-3047"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/3xxx/CVE-2026-3047.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-3047"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2441966"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-26T01:11:25.251462404Z"}}
