Usage PROHIBITED
(this CWE ID must not be used to map to real-world vulnerabilities)
Reason Grouping

Rationale

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

Comments

See member weaknesses of this category.
+ 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. The CWE Program will work with OWASP to improve these mappings, possibly requiring modifications to CWE itself.
