SCA: security update for github.com/openbao/openbao (GHSA-7ccv-rp6m-rffr)

low Tenable Self-Hosted Container Security Plugin ID 440689

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 2.5.3, OpenBao's
 Certificate authentication method, when a token renewal is requested and `disable_binding=true` is set,
 attempts to verify the current request's presented mTLS certificate matches the original. Token renewals
 for other authentication methods do not require any supplied login information. Due to incorrect matching,
 the certificate authentication method would allow renewal of tokens for which the attacker had a sibling
 certificate+key signed by the same CA, but which did not necessarily match the original role or the
 originally supplied certificate. This implies an attacker could still authenticate to OpenBao in a similar
 scope, however, token renewal implies that an attacker may be able to extend the lifetime of dynamic
 leases held by the original token. This attack requires knowledge of either the original token or its
 accessor. This vulnerability is original from HashiCorp Vault. This is addressed in v2.5.3. As a
 workaround, ensure privileged roles are tightly scoped to single certificates. (CVE-2026-39388)

Solution

Update the github.com/openbao/openbao library and its related packages to version 0.0.0-20260420160924-abe84e1af4c3 or later.
