* All strings used as file/directory names are now sanitized to address the path traversal vulnerabilities * Switched calls to utils.spinal_case to utils.kebab_case * Quotation marks are now escaped in all names/descriptions to address arbitrary code execution issues * Sanitized identifiers are now also checked for keyword collision * Added validation for default property values where possible Address arbitrary code execution vulnerability * Enum keys are now also sanitized * Update end_to_end_tests/fastapi_app/__init__.py Co-authored-by: Dylan Anthony <[email protected]> * Update openapi_python_client/parser/properties.py Co-authored-by: Dylan Anthony <[email protected]> * Changed NotImplementedErrors to ValidationErrors * Updated changelog * Fixed regex * Update openapi_python_client/utils.py Co-authored-by: Dylan Anthony <[email protected]> * Fixed rendering of union, datetime, and date properties. Added e2e test for all defaults * Fixed rendering of date/datetime default values when timezone is included * Simplified datetime rendering * Fixed typo * Readded support for DictProperty defaults and fixed a bug with json body template rendering * Fixed dict json body compatibility Co-authored-by: Ethan Mann <[email protected]> Co-authored-by: Dylan Anthony <[email protected]>

## 0.5.3 - Unreleased

### Security
10+
- All values that become file/directory names are sanitized to address path traversal vulnerabilities (CVE-2020-15141)
11+
- All values that get placed into python files (everything from enum names, to endpoint descriptions, to default values) are validated and/or saniziatied to address arbitrary code execution vulnerabilities (CVE-2020-15142)
12+
13+
### Changes
14+
- Due to security concerns/implementation complexities, default values are temporarily unsupported for any `RefProperty` that doesn't refer to an enum.
15+
- Defaults for properties must now be valid values for their respective type (e.g. "example string" is an invalid default for an `integer` type property, and the function for an endpoint using it would fail to generate and be skipped).
16+
917
### Additions
1018
- Added support for header parameters (#117)
