How to fix?

Upgrade org.wildfly.security:wildfly-elytron to version 1.6.8.Final or higher.

Overview

org.wildfly.security:wildfly-elytron is a new WildFly sub-project which is completely replacing the combination of PicketBox and JAAS as the WildFly client and server security mechanism.

Affected versions of this package are vulnerable to Access Restriction Bypass. The WildFlySecurityManager checks were bypassed when using custom security managers, resulting in an improper authorization. This flaw leads to information exposure by unauthenticated access to secure resources.
