PicketBoxBasedIdentity.exists() should check if a valid JAAS Subject exists instead of always returning true ------------------------------------------------------------------------------------------------------------ Key: WFLY-8908 URL: https://issues.jboss.org/browse/WFLY-8908 Project: WildFly Issue Type: Bug Components: Security Affects Versions: 11.0.0.Alpha1 Reporter: Stefan Guilhen Assignee: Stefan Guilhen The RealmIdentity.exists() method should be used to verify if a valid identity exists before an attempt to call other non-authentication methods - e.g. getAuthorizationIdentity() - is made. The PicketBoxBasedIdentity implementation in the SecurityDomainContextRealm is erroneously returning true when in fact it should be checking if a valid Subject was established as part of a previous JAAS authentication. The getAuthorizationIdentity() method can then simply throw an Exception if it is called without a valid JAAS Subject in place. Client code should check the result of the exists() method before attempting to get an AuthorizationIdentity so any code invoking getAuthorizationIdentity() without checking first if a valid identity exists should fail.
