# API Reference: Implementing API Schema Validation Security
|
|
|
|
## jsonschema (Python)
|
|
|
|
```python
|
|
import jsonschema
|
|
schema = {
|
|
"type": "object",
|
|
"properties": {
|
|
"name": {"type": "string", "maxLength": 100},
|
|
"email": {"type": "string", "format": "email"},
|
|
},
|
|
"required": ["name", "email"],
|
|
"additionalProperties": False, # Prevent mass assignment
|
|
}
|
|
jsonschema.validate(instance=payload, schema=schema)
|
|
```
|
|
|
|
## OpenAPI Security Checks
|
|
|
|
| Check | Risk | Severity |
|
|
|-------|------|----------|
|
|
| No request body schema | Injection | HIGH |
|
|
| additionalProperties: true | Mass assignment | MEDIUM |
|
|
| String without maxLength | Buffer overflow | MEDIUM |
|
|
| No response schema | Data exposure | MEDIUM |
|
|
| No security scheme | Broken auth | CRITICAL |
|
|
| Security explicitly disabled | Unauthenticated access | CRITICAL |
|
|
|
|
## OpenAPI Schema Best Practices
|
|
|
|
```yaml
|
|
components:
|
|
schemas:
|
|
User:
|
|
type: object
|
|
additionalProperties: false
|
|
properties:
|
|
name:
|
|
type: string
|
|
maxLength: 100
|
|
pattern: "^[a-zA-Z ]+$"
|
|
email:
|
|
type: string
|
|
format: email
|
|
maxLength: 255
|
|
required: [name, email]
|
|
```
|
|
|
|
## Spectral (OpenAPI Linter)
|
|
|
|
```bash
|
|
spectral lint openapi.yaml --ruleset .spectral.yaml
|
|
# Custom security rules in .spectral.yaml
|
|
```
