{"@ID": "1005", "@Name": "7PK - Input Validation and Representation", "@Status": "Draft", "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.

Security problems result from trusting input.\"", "Relationships": {"Has_Member": [{"@CWE_ID": "20", "@View_ID": "700"}, {"@CWE_ID": "77", "@View_ID": "700"}, {"@CWE_ID": "79", "@View_ID": "700"}, {"@CWE_ID": "89", "@View_ID": "700"}, {"@CWE_ID": "99", "@View_ID": "700"}]}, "References": {"Reference": {"@External_Reference_ID": "REF-6"}}, "Mapping_Notes": {"Usage": "Prohibited", "Rationale": "This entry is a Grouping.
