CVE ID : CVE-2026-1190
Published : Jan. 26, 2026, 8:16 p.m. | 1 hour, 29 minutes ago
Description : A flaw was found in Keycloak's SAML brokering functionality. When Keycloak is configured as a client in a Security Assertion Markup Language (SAML) setup, it fails to validate the `NotOnOrAfter` timestamp within the `SubjectConfirmationData`. This allows an attacker to delay the expiration of SAML responses, potentially extending the time a response is considered valid and leading to unexpected session durations or resource consumption.
Severity: 3.1 | LOW
