{"id":"CVE-2026-3047","summary":"Org.keycloak.broker.saml: keycloak saml broker: authentication bypass due to disabled saml client completing idp-initiated login","details":"A flaw was found in org.keycloak.broker.saml. 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.","aliases":["GHSA-8cr3-vpxx-92cx"],"modified":"2026-07-16T03:48:24.400459990Z","published":"2026-03-05T18:28:36.337Z","database_specific":{"cwe_ids":["CWE-305"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/3xxx/CVE-2026-3047.json","cna_assigner":"redhat"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/keycloak/keycloak","events":[{"introduced":"4cb4d2d06ed17e3a8bd928f472d3f9e4d1adea1d"},{"last_affected":"4e25e47b3c3619b3a0593448e1dfc0dd786cfbe1"}],"database_specific":{"extracted_events":[{"introduced":"26.2"},{"last_affected":"26.2"},{"introduced":"26.4"},{"last_affected":"26.4"}],"source":"CPE_STRING","cpe":["cpe:2.3:a:redhat:build_of_keycloak:26.2:*:*:*:*:*:*:*","cpe:2.3:a:redhat:build_of_keycloak:26.4:*:*:*:*:*:*:*"]}}],"versions":["26.2","26.4"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-3047.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
