CVE-2017-16100
If untrusted user input is allowed into the resolve() method then command injection is possible.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.05%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
