CVE-2021-20473
IBM Sterling File Gateway User Interface 2.2.0.0 through 6.1.1.0 does not invalidate session after logout which could allow an authenticated user to impersonate another user on the system.
Does this matter?
Lower severity and a low EPSS score (0.48%). Track it; it rarely justifies an emergency change on its own.
