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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:L/A:L","score":7.7},"cwes":["CWE-1287"],"references":["https://access.redhat.com/errata/RHSA-2026:3925","https://access.redhat.com/errata/RHSA-2026:3926","https://access.redhat.com/errata/RHSA-2026:3947","https://access.redhat.com/errata/RHSA-2026:3948","https://access.redhat.com/errata/RHSA-2026:76128"],"products":["redhat:build_of_keycloak"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-2092","score":0.00375,"percentile":0.31143,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-794g-x443-36f7","url":"https://osv.dev/vulnerability/GHSA-794g-x443-36f7","summary":"Keycloak: Unauthorized access via improper validation of encrypted SAML assertions","modified":"2026-10-26T15:00:05.428714525Z","packages":[{"ecosystem":"Maven","name":"org.keycloak:keycloak-services","purl":"pkg:maven/org.keycloak/keycloak-services","ranges":["<=26.2.5"],"fixed":[]},{"ecosystem":"Maven","name":"org.keycloak:keycloak-services","purl":"pkg:maven/org.keycloak/keycloak-services","ranges":[">=26.3.0 <=26.4.7"],"fixed":[]},{"ecosystem":"Maven","name":"org.keycloak:keycloak-services","purl":"pkg:maven/org.keycloak/keycloak-services","ranges":[">=26.5.0 <26.5.5"],"fixed":["26.5.5"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
