CVE-2018-16179
The Mizuho Direct App for Android version 3.13.0 and earlier does not verify server certificates, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.
Does this matter?
Lower severity and a low EPSS score (0.55%). Track it; it rarely justifies an emergency change on its own.
