CVE-2016-4740
Apple iOS before 10, when Handoff for Messages is used, does not ensure that a Messages signin has occurred before displaying messages, which might allow attackers to obtain sensitive information via unspecified vectors.
Does this matter?
Lower severity and a low EPSS score (0.31%). Track it; it rarely justifies an emergency change on its own.
