+ Vulnerability Mapping Notes


(this CWE ID must not be used to map to real-world vulnerabilities)

Reason: Category


This entry is a Category. Using categories for mapping has been discouraged since 2019. Categories are informal organizational groupings of weaknesses that can help CWE users with data aggregation, navigation, and browsing. However, they are not weaknesses in themselves.


See member weaknesses of this category.
+ Notes


As of CWE 4.6, the relationships in this category were pulled directly from the CWE mappings cited in the 2021 OWASP Top Ten. The CWE Program will work with OWASP to improve these mappings, possibly requiring modifications to CWE itself.
