Summary

The Common Weakness Enumeration (CEV) organization has released their 2022 Top 25 Most Dangerous Software Weaknesses list. This list demonstrates the most common and impactful software weaknesses occurring during the year of 2022. To create the list, the CWE Team leveraged Common Vulnerabilities and Exposures (CVE) data found within the National Institute of Standards and Technology (NIST) National Vulnerability Database (NVD) and the Common Vulnerability Scoring System (CVSS) scores associated with each CVE record, including a focus on CVE Records from the United States Cybersecurity and Infrastructure Security Agency (CISA) Known Exploited Vulnerabilities (KEV) Catalog.

Software architects, designers, developers, testers, users, project managers, security researchers, educators, and contributors to standards developing organizations (SDOs) are encouraged to utilize this list to mitigate risk within their organization, according to CWE.
