{"id":"BIT-keycloak-2026-2092","summary":"Keycloak-services: keycloak: unauthorized access via improper validation of encrypted saml assertions","details":"A flaw was found in Keycloak. 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.","aliases":["CVE-2026-2092","GHSA-794g-x443-36f7"],"modified":"2026-09-08T08:48:06.669722664Z","published":"2026-08-25T11:42:10.230Z","database_specific":{"cpes":["cpe:2.3:a:redhat:build_of_keycloak:*:*:*:*:*:*:*:*","cpe:2.3:a:keycloak:keycloak:*:*:*:*:*:*:*:*"],"severity":"High"},"references":[{"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-2026-2092"},{"type":"ADVISORY","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2437296"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-2092"},{"type":"ADVISORY","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-2092.json"}],"affected":[{"package":{"name":"keycloak","ecosystem":"Bitnami","purl":"pkg:bitnami/keycloak"},"ranges":[{"type":"SEMVER","events":[{"introduced":"26.2.0"},{"fixed":"26.2.14"},{"introduced":"26.4.0"},{"fixed":"26.4.10"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/keycloak/BIT-keycloak-2026-2092.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:L/A:L"}]}],"schema_version":"1.9.0"}
