Last year, K2 Cyber Security reported that the US-CERT Vulnerability Database hit a record number of vulnerabilities recorded for the fourth year in a row on December 15, 2020. As of last Thursday, October 14, 2021, the database is on track to hit a fifth record year of recorded vulnerabilities. The US-CERT Vulnerability Database keeps track of new vulnerabilities in production code as they are discovered and assigns each unique vulnerability with a “CVE” number. For the last four years, 2017 through 2020, we’ve had a record number of vulnerabilities recorded in the vulnerability database. For 2020, we recorded a total of 18,352 vulnerabilities (with 4,381 high, 11,205 medium and 2,766 low), the highest number recorded in any given year since tracking began.
