{"id":"CVE-2026-2092","aliases":["GHSA-794g-x443-36f7"],"url":"https://o3.security/vulnerability/CVE-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.","published":"2026-08-25T11:42:10.230Z","modified":"2026-09-08T08:48:06.669722664Z","cvss":null,"epss":{"score":0.00307,"percentile":0.23487,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Bitnami","name":"keycloak","fixedVersion":"26.2.14"}],"fix":null,"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-08T08:48:06.669722664Z"}}
