Does this matter?
Lower severity and a low EPSS score (9.20%). Track it; it rarely justifies an emergency change on its own.
Description
It was found that Samba before versions 4.5.3, 4.4.8, 4.3.13 always requested forwardable tickets when using Kerberos authentication. A service to which Samba authenticated using Kerberos could subsequently use the ticket to impersonate Samba to other services or domain users.
