When running in Appliance mode, a highly privileged authenticated attacker with access to SCP and SFTP may be able to bypass Appliance mode restrictions using undisclosed commands.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.44%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
