CVSS

7.1

Description

OpenBao is an open source identity-based secrets management system. Prior to version 2.5.4, OpenBao's namespaces provide multi-tenant separation. A tenant who intentionally leaks lease identifiers can have their lease and underlying credential revoked or renewed by a user in another tenant via the legacy, undocumented `sys/revoke` and `sys/renew` endpoints. This is fixed in OpenBao v2.5.4.
