Technical details
An insecure default initialization allows unrestricted creation and recreation of unauthenticated endpoints due to insufficient access controls. The vulnerability affects versions 6.4.0.0 through 6.6.1.0 and can be exploited over the network to allocate excessive resources or establish unauthorized authentication bypasses. The issue is mitigated by disabling unauthenticated endpoint creation or restricting it to a trusted network whitelist; version 6.6.2.0 adds a best practice warning for insecure configurations.
