CVE-2018-5258
The Neon app 1.6.14 iOS does not verify X.509 certificates from SSL servers, which allows remote attackers to spoof servers and obtain sensitive information via a crafted certificate.
Does this matter?
Lower severity and a low EPSS score (0.85%). Track it; it rarely justifies an emergency change on its own.
