References: CVE-2021- 28052
In older versions of HCP, a vulnerability in the multitenancy security model could allow unauthorized data access. Specifically:
(1) A tenant administrator may modify the configuration of a namespace in another tenant without authorization, potentially allowing unauthorized access to data in the other tenant.
(2) A tenant user (non-administrator) may view configuration of a namespace in another tenant without authorization.
In both cases, the unauthorized user must know the Namespace UUID of the targeted namespace.
