CVE-2019-12184
There is XSS in browser/components/MarkdownPreview.js in BoostIO Boostnote 0.11.15 via a label named flowchart, sequence, gallery, or chart, as demonstrated by a crafted SRC attribute of an IFRAME element, a different vulnerability than CVE-2019-12136.
Does this matter?
Lower severity and a low EPSS score (0.67%). Track it; it rarely justifies an emergency change on its own.
