NVD Description

Note: Versions mentioned in the description apply only to the upstream openbao package and not the openbao package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

OpenBao is an open source identity-based secrets management system. OpenBao's namespaces provide multi-tenant separation. Prior to version 2.5.3, a tenant who leaks token accessors can have their token revoked or renewed by a privileged administrator in another tenant. This is addressed in v2.5.3.
