Question: how many cves are there?
Answer: Vulnerability trends The number of vulnerabilities registered to the CVE database annually fluctuated within a narrow range between 2005 and 2016 – before jumping 128% from 6,447 in 2016 to 14,714 in 2017. That number climbed again to 16,556 in 2018 and 2019 is on course to reach a similar number.
