String Fields Left Boundary
| Item | Description |
|---|---|
| Full Fuzzer Name | StringFieldsLeftBoundaryFuzzer |
| Log Key | SFLB |
| Description | This fuzzer will send left boundary values in string fields. The expectation is that APIs will reject the request as invalid, as the value is shorter than the minLength. |
| Enabled by default? | Yes |
| Target field types | OpenAPI type string |
| Expected result when fuzzed field is required | 4XX |
| Expected result when fuzzed field is optional | 4XX |
| Expected result when fuzzed value is not matching field pattern | 4XX |
| Fuzzing logic | Iteratively replaces string fields with left boundary values: if the field has a defined minLength the fuzzer will generate an alphanumeric string of length minLength - 1, otherwise it will send an empty string |
| Conditions when this fuzzer will be skipped | When field is not of type string |
| HTTP methods that will be skipped | None |
