CVE-2026-112255 PUBLISHED

Endpoint credential minting (insecure default allow-list)

Assigner: OpenText
Reserved: 19.10.2026 Published: 29.10.2026 Updated: 29.10.2026

Initialization of a resource with an insecure default vulnerability in OpenText Advanced Authentication Server allows Excessive Allocation.

This issue affects Advanced Authentication Server: from 6.4.0.0 through 6.4.3.x, from 6.5.0.0 through 6.5.0.x, and from 6.6.0.0 through 6.6.1.0.

The fix for this is issue is to create a secure configuration.  The 6.6.2.0 release has a best practice entry if the configuration is unsecure.

A secure configuration is to NOT allow creation/recreation of Unauthenticated Endpoints.  If creation/recreation of Unauthenticated Endpoints is required, you should only allow it from trusted networks.  

To remedy this issue, change your configuration to NOT allow creation/recreation of Unauthenticated Endpoints. If you require Unauthenticated Endpoints, you MUST change your configuration to use a non-empty whitelist to specify the trusted networks.  An empty whitelist will allow all networks to create/recreate endpoints.
