CVE-2026-112255 · Severity: info · Published 2026-10-29

OpenText Advanced Authentication Server is used to verify user identities and control access to corporate systems. A default configuration flaw allows anyone on the network to create unauthenticated endpoints that bypass normal security controls. This could allow attackers to establish persistent backdoors or gain unauthorized access to protected resources without proper authentication.

## How to fix


Disable creation and recreation of unauthenticated endpoints in your configuration. If unauthenticated endpoints are required, configure a non-empty whitelist to restrict their creation to trusted networks only; an empty whitelist permits all networks.</anigation>
<parameter name="fixed_in">Advanced Authentication Server 6.6.2.0

## 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.
