HasMember	Base - a weakness that is still mostly independent of a resource or technology, but with sufficient details to provide specific methods for detection and prevention. Base level weaknesses typically describe issues in terms of 2 or 3 of the following dimensions: behavior, property, technology, language, and resource.	22	Improper Limitation of a Pathname to a Restricted Directory
HasMember	Base - a weakness that is still mostly independent of a resource or technology, but with sufficient details to provide specific methods for detection and prevention. Base level weaknesses typically describe issues in terms of 2 or 3 of the following dimensions: behavior, property, technology, language, and resource.	23	Relative Path Traversal
HasMember	Base - a weakness that is still mostly independent of a resource or technology, but with sufficient details to provide specific methods for detection and prevention. Base level weaknesses typically describe issues in terms of 2 or 3 of the following dimensions: behavior, property, technology, language, and resource.	36	Absolute Path Traversal
HasMember	Base - a weakness that is still mostly independent of a resource or technology, but with sufficient details to provide specific methods for detection and prevention. Base level weaknesses typically describe issues in terms of 2 or 3 of the following dimensions: behavior, property, technology, language, and resource.	59	Improper Link Resolution Before File Access
HasMember	Composite - a Compound Element that consists of two or more distinct weaknesses, in which all weaknesses must be present at the same time in order for a potential vulnerability to arise. Removing any of the weaknesses eliminates or sharply reduces the risk. One weakness, X, can be "broken down" into component weaknesses Y and Z. There can be cases in which one weakness might not be essential to a composite, but changes the nature of the composite when it becomes a vulnerability.	61	UNIX Symbolic Link (Symlink) Following

Vulnerability Mapping Notes

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 4.19, the relationships in this category were pulled directly from the CWE mappings cited in the 2025 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.
