CVE-2021-28052
A tenant administrator Hitachi Content Platform (HCP) may modify the configuration in another tenant without authorization, potentially allowing unauthorized access to data in the other tenant.
Does this matter?
Lower severity and a low EPSS score (0.77%). Track it; it rarely justifies an emergency change on its own.
