CVE-2018-3712
serve node module before 6.4.9 suffers from a Path Traversal vulnerability due to not handling %2e (.) and %2f (/) and allowing them in paths, which allows a malicious user to view the contents of any directory with known path.
Does this matter?
Lower severity and a low EPSS score (1.79%). Track it; it rarely justifies an emergency change on its own.
