CVE-2026-18572

Keycloak-services: keycloak-services: uma claim token can override authorization time-policy evaluation attributes PUBLISHED

Description (CNA)

Keycloak provides authorization services that allow administrators to restrict access to resources based on time policies (for example, only allowing access during business hours). A flaw was discovered where a user can include a fake time value in their authorization request that overrides the actual server time. This allows the user to bypass these time-based restrictions and access protected resources at unauthorized times.
