CVE-2019-9785
gitnote 3.1.0 allows remote attackers to execute arbitrary code via a crafted Markdown file, as demonstrated by a javascript:window.parent.top.require('child_process').execFile substring in the onerror attribute of an IMG element.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.68%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
