QID 580526: String Fields Exact Maximum Length Mismatch Schema

In this scenario fields of string type are updated with strings of exact maximum length as defined in the swagger file. If the maximum length is not defined for the string type this test is skipped. All string fields with a maximum length defined are updated iteratively and sent to the server. The expectation is that server will treat the requests as happy paths since the length of inserted strings matches the maximum. The purpose of the test is to verify that all defined boundaries are properly implemented. Based on the response using requests with valid values it is determined that the response to some valid values does not match schema definition for field being tested.

Enforcing maximum string length defined in swagger file will help provide clarity to the API users and avoid abuse of the API by hackers. API users might be confused with the response mismatch to valid values.

CVSS V3 rated as High - 6.5 severity.
