Keycloak's Security Assertion Markup Language (SAML) broker endpoint does not properly validate encrypted assertions when the overall SAML response is not signed. An attacker with a valid signed SAML assertion can exploit this by crafting a malicious SAML response. This allows the attacker to inject an encrypted assertion for an arbitrary principal, leading to unauthorized access and potential information disclosure.","severity":{"version":"3.1","score":7.7,"vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:L/A:L","level":"high","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-09","score":0.00383,"percentile":0.32601,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-1287"],"published":"2026-03-18T01:14:48Z","modified":"2026-10-26T15:00:05Z","fixes":[{"ecosystem":"Maven","package":"org.keycloak:keycloak-services","fixed_in":["26.5.5"],"sources":["ghsa","osv"]},{"ecosystem":"Bitnami","package":"keycloak","fixed_in":["26.2.14","26.4.10"],"sources":["osv"]}],"affected":[{"source":"ghsa","ecosystem":"Maven","package":"org.keycloak:keycloak-services","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"26.2.5"}]}]},{"source":"ghsa","ecosystem":"Maven","package":"org.keycloak:keycloak-services","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"26.3.0"},{"last_affected":"26.4.7"}]}]},{"source":"ghsa","ecosystem":"Maven","package":"org.keycloak:keycloak-services","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"26.5.0"},{"fixed":"26.5.5"}]}]},{"source":"osv","ecosystem":"Bitnami","package":"keycloak","ranges":[{"type":"SEMVER","events":[{"introduced":"26.2.0"},{"fixed":"26.2.14"},{"introduced":"26.4.0"},{"fixed":"26.4.10"}]}]},{"source":"osv","ecosystem":"Maven","package":"org.keycloak:keycloak-services","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"26.2.5"}]}],"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","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"]},{"source":"osv","ecosystem":"Maven","package":"org.keycloak:keycloak-services","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"26.3.0"},{"last_affected":"26.4.7"}]}],"versions":["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"]},{"source":"osv","ecosystem":"Maven","package":"org.keycloak:keycloak-services","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"26.5.0"},{"fixed":"26.5.5"}]}],"versions":["26.5.0","26.5.1","26.5.2","26.5.3","26.5.4"]},{"source":"osv","ecosystem":"Red

Keycloak's Security Assertion Markup Language (SAML) broker endpoint does not properly validate encrypted assertions when the overall SAML response is not signed. An attacker with a valid signed SAML assertion can exploit this by crafting a malicious SAML response. This allows the attacker to inject an encrypted assertion for an arbitrary principal, leading to unauthorized access and potential information disclosure.","status":"withdrawn","published":"2026-03-18T03:32:09Z","modified":"2026-10-06T18:45:07.396114662Z","cvss":[{"version":"3.1","score":7.7,"vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:L/A:L","level":"high"}],"cwes":["CWE-1287"],"updated_at":"2026-11-02T15:46:58.767335Z"},{"id":"RHSA-2026:76128","title":"Red Hat Security Advisory: Red Hat Single Sign-On 7.6.13 security update on RHEL 7","status":"published","published":"2026-10-07T10:19:58Z","modified":"2026-10-20T10:15:52Z","cvss":[{"version":"3.1","score":9.6,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:L","level":"critical"}],"updated_at":"2026-11-02T15:53:22.928316Z"},{"id":"RHSA-2026:76129","title":"Red Hat Security Advisory: Red Hat Single Sign-On 7.6.13 security update on RHEL 8","status":"published","published":"2026-10-07T10:19:59Z","modified":"2026-10-20T10:15:53Z","cvss":[{"version":"3.1","score":9.6,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:L","level":"critical"}],"updated_at":"2026-11-02T15:53:22.928316Z"},{"id":"RHSA-2026:76130","title":"Red Hat Security Advisory: Red Hat Single Sign-On 7.6.13 security update on RHEL 9","status":"published","published":"2026-10-07T10:19:59Z","modified":"2026-10-20T10:15:54Z","cvss":[{"version":"3.1","score":9.6,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:L","level":"critical"}],"updated_at":"2026-11-02T15:53:22.928316Z"},{"id":"BIT-keycloak-2026-2092","title":"Keycloak-services: keycloak: unauthorized access via improper validation of encrypted saml assertions","description":"A flaw was found in Keycloak.
