The underlying `requests` library automatically handles UTF-8 serialization. If raw, non-escaped JSON injection is strictly required, developers can manually pass a pre-serialized JSON string to the data parameter instead of a dictionary. +- [BREAKING] Removed unused HTTP exception classes (`AuthorizationError`, `ApiRateLimitError`, `DoesNotExistError`, `ValidationError`, `ActionDeniedError`). The SDK natively returns the `requests.Response` object for standard HTTP status codes (e.g., `400`, `401`, `404`), rendering these exceptions "dead code". Only genuine network drop exceptions (TimeoutError, etc.) remain. +- [BREAKING] Removed the `parse_response` and `logging_handler` utility functions. Logging is now integrated cleanly and automatically via Python's standard `logging` library. See the `README` for the new 2-line setup. - Redundant class constants (`API_REF`, `DEFAULT_API_URL`). +- Root `test.py` monolith (replaced by a modular test directory structure). + +### Pull Requests Merged + +- [PR_125](https://github.com/mailjet/mailjet-apiv3-python/pull/125) - Refactor client. ## [1.5.1] - 2025-07-14 diff --git a/mailjet_rest/client.py b/mailjet_rest/client.py index b8ec413..99464b4 100644 --- a/mailjet_rest/client.py +++ b/mailjet_rest/client.py @@ -2,21 +2,19 @@ The `mailjet_rest.client` module includes the core `Client` class for managing API requests, configuration, and error handling, as well as utility functions -and classes for building request headers, URLs, and parsing responses. +and classes for building URLs and managing endpoints.

Key additions & changes: - Resource Management: Implemented Context Managers (with Client(...)) for automatic TCP connection pooling and socket cleanup. - Smart Telemetry: Automatically extract Mailjet Trace IDs (CustomID, Campaign, TemplateID) and inject them into debug logs. - Advanced Timeouts: Upgraded the timeout parameter to accept tuple[float, float] and float, increasing the default to 60s to better handle heavy API operations (e.g., CSV imports, Content API). - Graceful Degradation: Llegacy exceptions (AuthorizationError, etc.), kwargs (ensure_ascii, data_encoding), and utility functions (parse_response), wrapping them in standard DeprecationWarnings. - Poka-Yoke Guardrails: Decoupled Magic Method Trap prevention into a pure utility function (validate_attribute_access). - Executable Documentation: Consolidated legacy smoke tests into smoke_readme_runner.py to dynamically test all README examples. - Documentation: Refactored README.md to follow DRY principles and highlight modern DX configurations. - CI/CD: Updated Dependabot groups and aligned GH Actions with master. - Testing: Added comprehensive unit tests for deprecations and context managers.

The underlying `requests` library automatically handles UTF-8 serialization. If raw, non-escaped JSON injection is strictly required, developers can manually pass a pre-serialized JSON string to the data parameter instead of a dictionary. -- [BREAKING] Removed unused HTTP exception classes (`AuthorizationError`, `ApiRateLimitError`, `DoesNotExistError`, `ValidationError`, `ActionDeniedError`). The SDK natively returns the `requests.Response` object for standard HTTP status codes (e.g., `400`, `401`, `404`), rendering these exceptions "dead code". Only genuine network drop exceptions (TimeoutError, etc.) remain. -- [BREAKING] Removed the `parse_response` and `logging_handler` utility functions. Logging is now integrated cleanly and automatically via Python's standard `logging` library. See the `README` for the new 2-line setup. +- Root `test.py` monolith (replaced by a modular `test/` directory structure). - Redundant class constants (`API_REF`, `DEFAULT_API_URL`). -- Root `test.py` monolith (replaced by a modular test directory structure). ### Pull Requests Merged diff --git a/README.md b/README.md index 9523d24..7b505c2 100644 --- a/README.md +++ b/README.md @@ -5,26 +5,18 @@ [![PyPI Version](https://img.shields.io/github/v/release/mailjet/mailjet-apiv3-python)](https://img.shields.io/github/v/release/mailjet/mailjet-apiv3-python) [![GitHub Release](https://img.shields.io/github/v/release/mailjet/mailjet-apiv3-python)](https://img.shields.io/github/v/release/mailjet/mailjet-apiv3-python) [![Python Versions](https://img.shields.io/badge/python-3.10%20%7C%203.11%20%7C%203.12%20%7C%203.13-blue)](https://github.com/mailjet/mailjet-apiv3-python) -[![License](https://img.shields.io/github/license/mailjet/mailjet-apiv3-python)](https://github.com/mailjet/mailjet-apiv3-python/blob/main/LICENSE) +[![License](https://img.shields.io/github/license/mailjet/mailjet-apiv3-python)](https://github.com/mailjet/mailjet-apiv3-python/blob/master/LICENSE) [![PyPI Downloads](https://img.shields.io/pypi/dm/mailjet-rest)](https://img.shields.io/pypi/dm/mailjet-rest) -[![Build Status](https://img.shields.io/github/actions/workflow/status/mailjet/mailjet-apiv3-python/commit_checks.yaml)](https://github.com/mailjet/mailjet-apiv3-python/actions) - +[![Build Status](https://img.shields.io/github/actions/workflow/status/mailjet/mailjet-apiv3-python/commit_checks.yaml)](https://github.com/mailjet/mailjet-apiv3-python) [![GitHub Stars](https://img.shields.io/github/stars/mailjet/mailjet-apiv3-python)](https://img.shields.io/github/stars/mailjet/mailjet-apiv3-python) [![GitHub Issues](https://img.shields.io/github/issues/mailjet/mailjet-apiv3-python)](https://img.shields.io/github/issues/mailjet/mailjet-apiv3-python) [![GitHub PRs](https://img.shields.io/github/issues-pr/mailjet/mailjet-apiv3-python)](https://img.shields.io/github/issues-pr/mailjet/mailjet-apiv3-python) -## Overview - -Welcome to the [Mailjet] official Python API wrapper!

It also expands the testing matrix to ensure forward compatibility. Key changes: Tooling Consolidation: Removed obsolete dependencies from environment-dev.yaml and pyproject.toml, establishing Ruff as the single source of truth. Config Cleanup: Purged dead configuration sections (tool.black, tool.flake8, tool.autopep8, tool.pydocstyle) from pyproject.toml. Ruff Alignment: Updated the Ruff ignore list to strictly preserve architectural constraints and prevent formatter conflicts (e.g., ISC001, COM812). Forward Compatibility: Added Python 3.14 to the GitHub Actions matrix and PyPI classifiers. Runtime Dependencies: Added typing-extensions to environment.yaml and environment-dev.yaml for robust cross-version type hinting support. Code Quality: Formatted code, removed unused imports (suppress), and stripped legacy migration comments from the smoke_readme_runner.py script.

Core Architectural Changes: Decoupled validation and routing logic into a dedicated mailjet_rest.utils.guardrails module (System Decomposition). Extracted payload preparation (_prepare_payload) and centralized logging (_log_response) from api_call to ensure Single Responsibility. Updated Smart Telemetry to include automatic log sanitization. Security Mitigations (Shift-Left): CWE-113 (CRLF Injection): Strict header validation to block HTTP Request Smuggling. CWE-117 (Log Forging): Mandatory telemetry sanitization via sanitize_log_trace. CWE-918 (SSRF): Hostname allow-listing in Config initialization to prevent credential exfiltration. CWE-601 (Open Redirect): Hard-disabled automatic redirects for all API calls. CWE-316 (Secret Leakage): Enhanced redaction in repr and str to prevent sensitive data in traces. Testing and Resilience: Modernized test suite to use pytest.warns for auditing security warnings instead of brittle log interception. Upgraded smoke_readme_runner with a safe_cleanup pattern to handle environmental 401 (permissions) and 404 (eventual consistency) errors. Fixed path traversal assertions to align with standard urllib.parse.quote behavior. Updated CHANGELOG.md with explicit CWE mapping for security auditing. --- CHANGELOG.md | 12 +- mailjet_rest/client.py | 271 ++++++++------- mailjet_rest/utils/guardrails.py | 108 +++++- pyproject.toml | 3 +- samples/smoke_readme_runner.py | 157 ++++++--- tests/integration/test_client.py | 12 + tests/unit/test_client.py | 564 ++++++++++++------------------- 7 files changed, 573 insertions(+), 554 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 70521dc..672e756 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -6,8 +6,13 @@ We [keep a changelog.](http://keepachangelog.com/) ### Security -- Prevented Path Traversal (CWE-22) vulnerabilities by enforcing strict URL encoding (`urllib.parse.quote`) on all dynamically injected path parameters (`id` and `action_id`). -- Prevented cleartext transmission (CWE-319) by enforcing strict `api_url` scheme validation (`https`) and hostname presence during `Config` initialization. +- **CWE-22 (Prevented Path Traversal):** Prevented vulnerabilities by enforcing strict URL encoding (`urllib.parse.quote`) on all dynamically injected path parameters (`id` and `action_id`). +- **CWE-113 (CRLF Injection):** Added strict header validation to block HTTP Request Smuggling. +- **CWE-117 (Log Forging):** Implemented mandatory sanitization of telemetry data. +- **CWE-316 (Secret Leakage):** Enhanced `__repr__` and `__str__` to prevent sensitive data from appearing in stack traces. +- **CWE-319 (Cleartext transmission):** Prevented by enforcing strict `api_url` scheme validation (`https`) and hostname presence during `Config` initialization. +- **CWE-601 (Open Redirect):** Hard-disabled automatic redirects (`allow_redirects=False`) for all API calls. +- **CWE-918 (SSRF):** Added hostname validation to prevent credential exfiltration to non-Mailjet domains. - Added comprehensive security scanning to the CI/CD pipeline (`bandit`, `semgrep`, `gitleaks`, `detect-secrets`). - Updated `SECURITY.md` policy to clarify supported active branches. @@ -16,6 +21,9 @@ We [keep a changelog.](http://keepachangelog.com/) - Official support for Python 3.14 (added to CI test matrix and PyPI classifiers). - Runtime dependency `typing-extensions>=4.7.1` for Python versions `<3.11` to support modern type hinting. - Context Managers (Resource Management): The `Client` now supports the `with` statement (`__enter__` / `__exit__`) for automatic TCP connection pooling and socket cleanup, preventing resource leaks. +- New `mailjet_rest.utils.guardrails` module for centralized security and routing validation. +- `sanitize_log_trace` utility to protect against Log Forging attacks. +- Proactive `UserWarning` for insecure TLS configurations and unencrypted HTTP proxies. - Smart Telemetry: The SDK now automatically extracts Mailjet Trace IDs (`CustomID`, `Campaign`, `TemplateID`) from payloads and headers, injecting them into debug logs for easier correlation with the Mailjet Dashboard. - Executable Documentation: Added `samples/smoke_readme_runner.py` as a dynamic test suite to guarantee all `README.md` examples are continuously validated and functional against the live API. - Developer Experience (DX) Guardrails: The SDK now logs explicit warnings when encountering ambiguous routing configurations (e.g., using the singular `template` resource on Content API `v1`, or attempting to route the Send API outside of `v3`/`v3.1`). diff --git a/mailjet_rest/client.py b/mailjet_rest/client.py index bd8d4b3..c65316a 100644 --- a/mailjet_rest/client.py +++ b/mailjet_rest/client.py @@ -17,7 +17,6 @@ from typing import Any from typing import Literal from urllib.parse import quote -from urllib.parse import urlparse import requests # pyright: ignore[reportMissingModuleSource] from requests.adapters import HTTPAdapter @@ -27,7 +26,12 @@ from urllib3.util.retry import Retry from mailjet_rest._version import __version__ +from mailjet_rest.utils.guardrails import check_request_security +from mailjet_rest.utils.guardrails import sanitize_log_trace from mailjet_rest.utils.guardrails import validate_attribute_access +from mailjet_rest.utils.guardrails import validate_config_url +from mailjet_rest.utils.guardrails import validate_crlf_headers +from mailjet_rest.utils.guardrails import validate_dx_routing if TYPE_CHECKING: @@ -121,12 +125,11 @@ def parse_response(response: requests.Response, debug: bool = False) -> dict[str Returns: dict[str, Any] | str: The parsed JSON dictionary or raw text string.

Memory Density & Speed (__slots__) + +We have implemented `__slots__` across the core `Client`, `Config`, and `Endpoint` classes. + +- **RAM Footprint:** By removing the dynamic `__dict__`, we reduced the memory overhead of every instantiated client. +- **Attribute Access:** `__slots__` provides faster attribute access than a standard dictionary-backed class, which is critical for the SDK's dynamic routing engine. + +### 2. High-Speed Dynamic Routing (Endpoint Caching) + +The SDK utilizes a lazy-loading cache for API endpoints. + +- **O(1) Resolution:** Once an endpoint (like `client.contact`) is accessed, it is cached in an instance-level dictionary.
