SCA: security update for github.com/openbao/openbao (GHSA-mwr2-wmgp-crj6)

low Tenable Cloud Security Plugin ID 443695

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 2.5.5, OpenBao users granted
 capabilities on /sys/namespaces/root within a non-root namespace could exploit special handling of the
 literal root path in namespace canonicalization. The /sys/namespaces/* endpoint family can resolve its
 containing namespace through a path prefix or X-Vault-Namespace header. ACL checks occurred before root
 canonicalized to an empty path, causing /sys/namespaces/root to resolve to the system backend's containing
 namespace and allowing permitted lookups, deletion, locking, or custom metadata changes against that
 direct containing namespace. The root namespace and arbitrary unrelated namespaces are not affected, and
 available operations depend on the capabilities granted on the path and subpaths such as /api-lock. This
 issue is fixed in version 2.5.5. (CVE-2026-55775)

Solution

Update the github.com/openbao/openbao library and its related packages to version 0.0.0-20260617103935-d3c1cc64b1ae or later.
