Remote attackers can perform a command Injection attack and execute arbitrary commands after logging in with the privileged permission.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.79%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
