CVE_2018_4993_GOTOE_UNC
What it means
PDF automatic/open action uses GoToE or GoToR with a UNC /F target.
Why it fires
This is the tighter Adobe Reader NTLM credential-leak shape: an /AA or /OpenAction-triggered GoToE/GoToR action whose /F file target is a UNC path. That matches the public CVE-2018-4993 proof-of-concept pattern more closely than the broader UNC-in-action rule.
