+ Notes

Maintenance

As of CWE 4.6, the relationships in this category were pulled directly from the CWE mappings cited in the 2021 OWASP Top Ten. These mappings include categories, which are discouraged for mapping, as well as high-level weaknesses such as Pillars. The CWE Program will work with OWASP to improve these mappings, possibly requiring modifications to CWE itself.
