A flaw in Keycloak causes OpenID Connect token introspection to improperly evaluate revocation state when both realm-level and client-level notBefore policies are configured. In this condition, the introspection logic honors the client-level notBefore setting but fails to correctly enforce the realm-level notBefore value, allowing tokens that should be considered revoked at the realm scope to still be reported as active. This affects deployments using Keycloak as an identity and access management provider and relying on OIDC introspection to validate token status.
