CVE-2016-5253
The Updater in Mozilla Firefox before 48.0 on Windows allows local users to write to arbitrary files via vectors involving the callback application-path parameter and a hard link.
Does this matter?
Lower severity and a low EPSS score (0.24%). Track it; it rarely justifies an emergency change on its own.
