NewCVE-2025-55001  (opens in a new tab)
CWE-156  (opens in a new tab)

How to fix?

Upgrade github.com/openbao/openbao/vault to version 2.3.2 or higher.

Overview

Affected versions of this package are vulnerable to Improper Neutralization via the username_as_alias parameter in the LDAP authentication process. An attacker can gain unauthorized access to resources protected by multi-factor authentication by supplying a crafted username that bypasses alias-specific enforcement. This is only exploitable if the username_as_alias=true parameter is enabled in the LDAP authentication configuration.

Workaround

This vulnerability can be mitigated by removing all usage of the username_as_alias=true parameter and updating any entity aliases accordingly.
