CWE Over Time
The two visualizations on this page are simple graphs which provide different views of how the assignment of vulnerabiility types has changed over time.
Relative Vulnerability Type Totals By Year
The vulnerabilties in the NVD are assigned a CWE based on a slice of the total CWE Dictionary. The visualization below shows a stacked bar graph of the total number of vulnerabilities assigned a CWE for each year. It is possible (although not common) that a vulnerability has multiple CWEs assigned.
Vulnerability Type Change By Year
This visualization is a slightly different view that emphasizes how the assignment of CWEs has changed from year to year.
