Grouping ID: 1453
Vulnerability Mapping: PROHIBITED This CWE ID must not be used to map to real-world vulnerabilities
+ Summary
Weaknesses in this category are related to the rules and recommendations in section "03 Numbers" of the OpenSSF Secure Coding Guide for Python.

Nature Type ID Name
MemberOf ViewView - a subset of CWE entries that provides a way of examining CWE content. The two main view structures are Slices (flat lists) and Graphs (containing relationships between entries). 1449 Weaknesses Addressed by the OpenSSF Secure Coding Guide for Python (2026)
HasMember BaseBase - 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. 190 Integer Overflow or Wraparound

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.
