SCA: security update for github.com/openbao/openbao (GHSA-cpj3-3r2f-xj59)

critical Tenable Self-Hosted Container Security Plugin ID 439337

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- OpenBao is an open source identity-based secrets management system. Prior to version 2.5.2, OpenBao
installations that have an OIDC/JWT authentication method enabled and a role with `callback_mode=direct`
configured are vulnerable to XSS via the `error_description` parameter on the page for a failed
authentication. This allows an attacker access to the token used in the Web UI by a victim. The
`error_description` parameter has been replaced with a static error message in v2.5.2. The vulnerability
can be mitigated by removing any roles with `callback_mode` set to `direct`. (CVE-2026-33758)

Solution

Update the github.com/openbao/openbao library and its related packages to version 0.0.0-20260325133417-6e2b2dd84f0e or later.
