SCA: security update for github.com/openbao/openbao (GHSA-8w8f-r2xv-4q4j)

medium Tenable Self-Hosted Container Security Plugin ID 443678

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, an authenticated
 OpenBao caller with write access to transit/keys/* could terminate the server process by setting derived
 to true while the type parameter selected rsa-, ecdsa-, or ed25519. The Transit policy creation path in
 builtin/logical/transit/backend.go and sdk/helper/keysutil/policy.go could reach an error path that
 double-unlocked a mutex while handling this invalid asymmetric derived-key combination, causing a panic,
 no HTTP response, process exit, and denial of service. JSON and HCL key-creation requests can express the
 triggering combination. This issue is fixed in version 2.5.5. (CVE-2026-55776)

Solution

Update the github.com/openbao/openbao library and its related packages to version 0.0.0-20260617104123-db57c62602b2 or later.
