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.\n\n## Affected\n\n- `build_of_keycloak >= 26.2, < 26.2.14`\n- `build_of_keycloak >= 26.4, < 26.4.10`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `build_of_keycloak 26.4.10`\n\n## Package advisory (CVE-2026-2092)\n\nAffected packages:\n\n- `org.keycloak:keycloak-services <= 26.2.5`\n- `org.keycloak:keycloak-services >= 26.3.0, <= 26.4.7`\n- `org.keycloak:keycloak-services >= 26.5.0, < 26.5.5`\n\nSource: https://github.com/advisories/GHSA-794g-x443-36f7\n\n## Vendor advisories\n\n- **RHSA-2026:76134** · Red Hat · fixed in: Middleware Containers for OpenShift · released 2026-10-05 · [advisory](https://access.redhat.com/errata/RHSA-2026:76134)\n- **RHSA-2026:3925** · Red Hat · fixed in: Red Hat build of Keycloak 26.2 · released 2026-03-05 · [advisory](https://access.redhat.com/errata/RHSA-2026:3925)\n- **RHSA-2026:3948** · Red Hat · fixed in: Red Hat build of Keycloak 26.4 · released 2026-03-05 · [advisory](https://access.redhat.com/errata/RHSA-2026:3948)\n- **RHSA-2026:76132** · Red Hat · fixed in: Red Hat Single Sign-On 7.6.13 · released 2026-10-05 · [advisory](https://access.redhat.com/errata/RHSA-2026:76132)\n- **RHSA-2026:3926** · Red Hat · fixed in: Red Hat build of Keycloak 26.2.14 · released 2026-03-05 · [advisory](https://access.redhat.com/errata/RHSA-2026:3926)\n- **RHSA-2026:3947** · Red Hat · fixed in: Red Hat build of Keycloak 26.4.10 · released 2026-03-05 · [advisory](https://access.redhat.com/errata/RHSA-2026:3947)","depth":"twilight","depthScore":42,"depthScoreParts":{"impact":42.4,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
