Overview

org.wildfly:wildfly-ejb3 is a WildFly Application Server

Affected versions of this package are vulnerable to Improper Access Control when returning an incorrect caller principal under certain heavily concurrent situations when Elytron Security is used. This flaw allows an attacker to gain improper access to information they should not have.

Note: JBoss EAP 7.1 until 7.4 is not affected by default as it comes with Legacy Security enabled out-of-the-box.
