Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.8.

A proof-of-concept (PoC) exploit exists for CVE-2018-20580. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
