CVE-2018-15728
Couchbase Server exposed the '/diag/eval' endpoint which by default is available on TCP/8091 and/or TCP/18091.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.92%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
