Since this week marks the start of the 2nd quarter, I figured it would be interesting to see where we are with the number of CVEs published this year.

Since January 1st, 2021, the NVD has published:

2792 CVEs 

31 Per Day

The five busiest publishing dates were: 

2021-01-20    201

2021-01-12    127

2021-01-13    126

2021-03-11    107

2021-02-04     92

CVEs published per day in Q1 2021

How does this compare to CVEs published in Q1 2020  

From January 1st, 2020 to April 1st, 2020, there were:

2484 CVEs

27 Per Day

7.11 Average CVSS 3 Score

27.2 Average Kenna Risk Score. 

The five busiest publishing dates in the 1st quarter last year were: 

2020-03-12    284

2020-01-15    228

2020-02-11    163

2020-03-25    100

2020-02-13     79

Looking Ahead

In Q1 of 2020, 15% of CVEs were published (2484 of 15789). If that number were to hold for this year, we are looking at over 17800 CVEs this year (although I would bet the over).  Here is a Jupyter notebook you can use to get access to the full data set:
