An authenticated attacker can perform Server-Side Request Forgery (SSRF) by manipulating the `client_session_host` parameter during refresh token requests. This occurs when a Keycloak client is configured to use the `backchannel.logout.url` with the `application.session.host` placeholder. Successful exploitation allows the attacker to make HTTP requests from the Keycloak server’s network context, potentially probing internal networks or internal APIs, leading to information disclosure.","affected":[{"package":{"name":"org.keycloak:keycloak-services","ecosystem":"Maven","purl":"pkg:maven/org.keycloak/keycloak-services"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"26.5.0"},{"fixed":"26.6.3"}]}],"versions":["26.5.0","26.5.1","26.5.2","26.5.3","26.5.4","26.5.5","26.5.6","26.5.7","26.6.0","26.6.1","26.6.2"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-22rm-wp4x-v5cx/GHSA-22rm-wp4x-v5cx.json"}},{"package":{"name":"org.keycloak:keycloak-services","ecosystem":"Maven","purl":"pkg:maven/org.keycloak/keycloak-services"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"26.4.13"}]}],"versions":["1.0-alpha-1","1.0-alpha-1-12062013","1.0-alpha-2","1.0-alpha-3","1.0-alpha-4","1.0-beta-1","1.0-beta-1-20150521","1.0-beta-1-20150523","1.0-beta-2","1.0-beta-3","1.0-beta-4","1.0-final","1.0-rc-1","1.0-rc-2","1.0.1.Final","1.0.2.Final","1.0.3.Final","1.0.4.Final","1.0.5.Final","1.1.0.Beta1","1.1.0.Beta2","1.1.0.Final","1.1.1.Final","1.2.0.Beta1","1.2.0.CR1","1.2.0.Final","1.3.0.Final","1.3.1.Final","1.4.0.Final","1.5.0-Final","1.5.0.Final","1.5.1.Final","1.6.0.Final","1.6.1.Final","1.7.0.CR1","1.7.0.Final","1.8.0.Alpha1","1.8.0.CR1","1.8.0.CR2","1.8.0.CR3","1.8.0.Final","1.8.1.Final","1.9.0.CR1","1.9.0.Final","1.9.1.Final","1.9.2.Final","1.9.3.Final","1.9.4.Final","1.9.5.Final","1.9.7.Final","1.9.8.Final","10.0.0","10.0.1","10.0.2","11.0.0","11.0.1","11.0.2","11.0.3","12.0.0","12.0.1","12.0.2","12.0.3","12.0.4","13.0.0","13.0.1","14.0.0","15.0.0","15.0.1","15.0.2","15.1.0","15.1.1","16.0.0","16.1.0","16.1.1","17.0.0","17.0.1","18.0.0","18.0.1","18.0.2","19.0.0","19.0.1","19.0.2","19.0.3","2.0.0.CR1","2.0.0.Final","2.1.0.CR1","2.1.0.Final","2.2.0.CR1","2.2.0.Final","2.2.1.Final","2.3.0.CR1","2.3.0.Final","2.4.0.CR1","2.4.0.Final","2.5.0.CR1","2.5.0.Final","2.5.1.Final","2.5.4.Final","2.5.5.Final","20.0.0","20.0.1","20.0.2","20.0.3","20.0.4","20.0.5","21.0.0","21.0.1","21.0.2","21.1.0","21.1.1","21.1.2","22.0.0","22.0.1","22.0.2","22.0.3","22.0.4","22.0.5","23.0.0","23.0.1","23.0.2","23.0.3","23.0.4","23.0.5","23.0.6","23.0.7","24.0.0","24.0.1","24.0.2","24.0.3","24.0.4","24.0.5","25.0.0","25.0.1","25.0.2","25.0.3","25.0.4","25.0.5","25.0.6","26.0.0","26.0.1","26.0.2","26.0.3","26.0.4","26.0.5","26.0.6","26.0.7","26.0.8","26.1.0","26.1.1","26.1.2","26.1.3","26.1.4","26.1.5","26.2.0","26.2.1","26.2.2","26.2.3","26.2.4","26.2.5","26.3.0","26.3.1","26.3.2","26.3.3","26.3.4","26.3.5","26.4.0","26.4.1","26.4.2","26.4.3","26.4.4","26.4.5","26.4.6","26.4.7","3.0.0.CR1","3.0.0.Final","3.1.0.CR1","3.1.0.Final","3.2.0.CR1","3.2.0.Final","3.2.1.Final","3.3.0.CR1","3.3.0.CR2","3.3.0.Final","3.4.0.CR1","3.4.0.Final","3.4.1.CR1","3.4.1.Final","3.4.2.Final","3.4.3.Final","4.0.0.Beta1","4.0.0.Beta2","4.0.0.Beta3","4.0.0.Final","4.1.0.Final","4.2.0.Final","4.2.1.Final","4.3.0.Final","4.4.0.Final","4.5.0.Final","4.6.0.Final","4.7.0.Final","4.8.0.Final","4.8.1.Final","4.8.2.Final","4.8.3.Final","5.0.0","6.0.0","6.0.1","7.0.0","7.0.1","8.0.0","8.0.1","8.0.2","9.0.0","9.0.2","9.0.3"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-22rm-wp4x-v5cx/GHSA-22rm-wp4x-v5cx.json"}}],"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-4874"},{"type":"WEB","url":"https://github.com/keycloak/keycloak/issues/47935"},{"type":"WEB","url":"https://github.com/keycloak/keycloak/pull/49682"},{"type":"WEB","url":"https://github.com/keycloak/keycloak/pull/49685"},{"type":"WEB","url":"https://github.com/keycloak/keycloak/commit/00dd0dd716c4319d3bac3eb2f2ac22d2a94f79fd"},{"type":"WEB","url":"https://github.com/keycloak/keycloak/commit/63de0efd351a7a684212a042a12271908f63f0ee"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:25097"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:25098"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:30049"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:30050"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-4874"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2451611"},{"type":"PACKAGE","url":"https://github.com/keycloak/keycloak"}],"database_specific":{"cwe_ids":["CWE-918"],"github_reviewed":true,"github_reviewed_at":"2026-03-27T20:03:17Z","nvd_published_at":"2026-03-26T08:16:22Z","severity":"LOW"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N"}]} |
