Briefly, this error occurs when Elasticsearch’s built-in security features, such as authentication and encryption, are not enabled. This leaves your cluster vulnerable to unauthorized access. To resolve this, you can enable Elasticsearch’s built-in security features by setting ‘xpack.security.enabled’ to true in the elasticsearch.yml configuration file. Additionally, you should also set up user authentication and role-based access control to further secure your cluster.

We extracted the following from Elasticsearch source code for those seeking an in-depth context :
final boolean newState = licenseState.isSecurityEnabled();
// old state might be null (undefined) so do Object comparison
if (Objects.equals(newState; securityEnabled) == false) {
logger.info("Active license is now [{}]; Security is {}"; licenseState.getOperationMode(); newState ? "enabled" : "disabled");
