CWE Grouping: 7PK - Input Validation and Representation
Grouping ID: 1005
Vulnerability Mapping:PROHIBITEDThis CWE ID must not be used to map to real-world vulnerabilities
Summary
This category represents one of the phyla in the Seven Pernicious Kingdoms vulnerability classification. It includes weaknesses that exist when an application does not properly validate or represent input. According to the authors of the Seven Pernicious Kingdoms, "Input validation and representation problems are caused by metacharacters, alternate encodings and numeric representations. Security problems result from trusting input."

View - 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).
Class - a weakness that is described in a very abstract fashion, typically independent of any specific language or technology. More specific than a Pillar Weakness, but more general than a Base Weakness. Class level weaknesses typically describe issues in terms of 1 or 2 of the following dimensions: behavior, property, and resource.

Class level weaknesses typically describe issues in terms of 1 or 2 of the following dimensions: behavior, property, and resource.
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.

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.
