CVE-2026-40264

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.
