2020 vulnerability disclosures are on track to exceed 2019 despite a sharp decrease of 19.2% observed earlier in the year. Risk Based Security aggregated 23,269 vulnerabilities disclosed during 2020. Despite the initial disruption from COVID-19, the trend of total number of vulnerabilities suggests that business operations and routines have normalized as the gap has closed to 0.98%. CVE continues to fall behind in coverage. Organizations relying on CVE/NVD may struggle to justify that gap to auditors and management.
