CVE-2018-4278
In Safari before 11.1.2, iTunes before 12.8 for Windows, iOS before 11.4.1, tvOS before 11.4.1, iCloud for Windows before 7.6, sound fetched through audio elements may be exfiltrated cross-origin.
Does this matter?
Lower severity and a low EPSS score (2.28%). Track it; it rarely justifies an emergency change on its own.
