Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (1.19%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

Kiteworks Email Protection Gateway did not sufficiently validate the content of an uploaded backup, and allowed an administrator to influence how the application loaded it. An authenticated administrator could potentially use this to execute arbitrary code on the gateway as the underlying service account.
