Security (CWE-22): - Mitigated Path Traversal vulnerabilities in Endpoint._build_url. Dynamic URI template variables (e.g., {id}, {action_id}) are now strictly sanitized via urllib.parse.quote(safe=) prior to regex interpolation. Architecture & DX: - Added mailjet_rest/routes.py containing an immutable MappingProxyType registry defining exact API versions and paths for all resources. - Introduced TemplateContentBuilder with fail-fast Boundary Parsing to enforce schema correctness before network execution. - Removed legacy _DYNAMIC_ENDPOINTS tuple, completely decoupling the Client from hardcoded resource lists. Testing: - Deployed a data-driven, parameterized test suite covering 50+ registry combinations, proving 100% parity with legacy routing logic and explicit separation between Content API (v1) and Email API (v3). --- mailjet_rest/builders.py | 86 +++++++++++++++++ mailjet_rest/client.py | 63 +++--------- mailjet_rest/endpoint.py | 48 +++++++++- mailjet_rest/routes.py | 121 +++++++++++++++++++++++ mailjet_rest/utils/guardrails.py | 18 ++++ tests/unit/test_builders.py | 29 +++++- tests/unit/test_client.py | 159 +++++++++++++++++++++++++++++++ 7 files changed, 471 insertions(+), 53 deletions(-) create mode 100644 mailjet_rest/routes.py diff --git a/mailjet_rest/builders.py b/mailjet_rest/builders.py index 0140218..befc059 100644 --- a/mailjet_rest/builders.py +++ b/mailjet_rest/builders.py @@ -118,6 +118,18 @@ def set_content(self, text: str | None = None, html: str | None = None) -> Self: self._msg["HTMLPart"] = html return self + def set_headers(self, headers: dict[str, str]) -> Self: + """Set custom headers (e.g., Reply-To, X-Custom). + + Args: + headers (dict[str, str]): Custom key-value string pairs. + + Returns: + Self: The builder instance for method chaining. + """ + self._msg["Headers"] = headers + return self + def set_template(self, template_id: int, enable_language: bool = True) -> Self: """Use a pre-defined Mailjet Template. @@ -188,3 +200,77 @@ def build(self) -> SendV31Message: raise ValueError(msg) return self._msg # type: ignore[return-value] + + +class TemplateContentBuilder: + """Builder for /template/{id}/contents API payloads.""" + + __slots__ = ("_data",) + + def __init__(self) -> None: + """Initialize an empty template contents data payload descriptor.""" + self._data: dict[str, Any] = {} + + def set_meta(self, author: str | None = None, name: str | None = None, locale: str = "en_US") -> Self: + """Set core template identity and structural configuration attributes. + + Args: + author (str | None): Optional author identifier name. + name (str | None): Optional unique template layout identifier name. + locale (str): Language and country locale definition (default: "en_US"). + + Returns: + Self: The builder instance for method chaining. + """ + if author: + self._data["Author"] = author + if name: + self._data["Name"] = name + self._data["Locale"] = locale + return self + + def set_content(self, text: str | None = None, html: str | None = None, mjml: str | None = None) -> Self: + """Set content keys as per API documentation. + + Args: + text (str | None): Plain text part component. + html (str | None): Rendered raw HTML layout sequence. + mjml (str | None): Semantic responsive MJML markup representation. + + Returns: + Self: The builder instance for method chaining. + """ + if text: + self._data["TextPart"] = text + if html: + self._data["HTMLPart"] = html + if mjml: + self._data["MJMLPart"] = mjml + return self + + def set_headers(self, headers: dict[str, str]) -> Self: + """Sets the Headers JSON object structure crossing the ingress gate. + + Args: + headers (dict[str, str]): Custom key-value structural protocol attributes. + + Returns: + Self: The builder instance for method chaining. + """ + self._data["Headers"] = headers + return self + + def build(self) -> dict[str, Any]: + """Validate and return the completed templates engine schema dictionary. + + Returns: + dict[str, Any]: Fully validated parsed dynamic payload payload mapping. + + Raises: + ValueError: If no valid text, html or mjml boundary tokens are passed. + """ + if not any(k in self._data for k in ("TextPart", "HTMLPart", "MJMLPart")): + msg = "Template validation failed: At least one of text, html, or mjml content is required." + raise ValueError(msg) + + return self._data diff --git a/mailjet_rest/client.py b/mailjet_rest/client.py index af1ff3a..46772ac 100644 --- a/mailjet_rest/client.py +++ b/mailjet_rest/client.py @@ -34,6 +34,7 @@ from mailjet_rest.errors import MailjetAuthError from mailjet_rest.errors import TimeoutError # noqa: A004 from mailjet_rest.errors import ValidationError +from mailjet_rest.routes import ROUTE_MAP from mailjet_rest.types import _ALLOWED_TRACE_FIELDS from mailjet_rest.utils.guardrails import RedactingFilter from mailjet_rest.utils.guardrails import SecureHTTPAdapter @@ -171,50 +172,6 @@ class Client: respect_retry_after_header=True, # To prevent aggressive polling ) -

**Enterprise Runtime Security:** Added opt-in PEP 578 Audit Hooks (`sys.addaudithook`) managed via the new `Config` class attribute `enable_security_audit` to monitor runtime network events (`mailjet.security.*`) for SIEM/SecOps compliance. +- **Path Traversal Mitigation (CWE-22)**: Implemented strict path segment sanitization in `Endpoint` and `guardrails.py` using `urllib.parse.quote(safe="")` to prevent directory traversal via dynamic ID inputs. +- **Runtime Security**: Centralized and hardened `SecurityGuard.sanitize_segment` to neutralize potential CRLF injections and path traversal attempts across the entire request stack. - **Supply Chain Security:** Hardened the GitHub Actions validation pipeline by implementing Google's `osv-scanner` and separating `pip-audit` into an independent strict security job. - **Static Analysis Hardening:** Expanded Semgrep scanning targets to include the `p/insecure-transport` extended query suite and wired internal Bandit configuration (`-c pyproject.toml`) directly into CI workflow checkpoints. - **Automated Fuzzing:** Integrated `Atheris` (libFuzzer engine) code coverage suite into development workflows, exposing a unified orchestration entry point (`manage.sh fuzz_all`). @@ -14,6 +16,10 @@ We [keep a changelog.](http://keepachangelog.com/) ### Added +- **Registry-Based Routing**: Implemented O(1) immutable routing registry (`ROUTE_MAP`) for static endpoint resolution, significantly reducing dynamic attribute lookup overhead. +- **TemplateContentBuilder**: Introduced a dedicated fluent builder for `Content API` payloads, enforcing schema correctness with fail-fast validation. +- **URI Templating Engine**: Added a robust path interpolation engine in `Endpoint` to handle complex multi-level REST resources dynamically without handler proliferation. +- **Telemetry Infrastructure**: Enhanced internal telemetry extraction for better structured logging of API request payloads. - **Domain Configuration:** Extracted configuration logic out of the monolithic client layout into a dedicated `Config` structure (`mailjet_rest/config.py`) to safely isolate runtime parameters. - **Testing Ecosystem:** Segmented the testing footprint into clear execution topologies: `tests/unit/` (100% offline via mock patches), `tests/integration/` (live network testing), `tests/regression/`, and `tests/fuzz/` (Atheris mutations). - **Error Boundaries:** Introduced a dedicated `errors.py` module containing explicit, domain-specific leave exceptions (`ValidationError`, `MailjetAuthError`, `ApiRateLimitError`, etc.) to avoid catching bare exceptions. @@ -21,10 +27,20 @@ We [keep a changelog.](http://keepachangelog.com/) ### Changed +- **Performance Optimization**: + - Migrated from procedural dynamic routing (`__getattr__`) to O(1) static lookups. + - Refactored internal string manipulations to use native Python methods, reducing cold-boot latency by ~29ms. + - Optimized memory footprint by enforcing `__slots__` across core infrastructure classes (`Client`, `Endpoint`, `Config`). +- **Configuration**: Standardized `Config` structure and moved internal type aliases to `types.py` to prevent cyclic import dependencies. +- **Dependency Management**: Updated `pyproject.toml` to optimize `ruff` linting and import grouping (isort). - **Architectural Decomposition (SRP):** Refactored the bloated `client.py` component, shifting single-responsibility concerns into individual domain files (`builders.py`, `config.py`, `endpoint.py`, `errors.py`, `types.py`). - **Endpoint Routing Interface:** Relaxed the internal route handler signature `_route_data` inside `endpoint.py` by converting the explicit name identifier to an optional parameter (`_name: str | None = None`) to increase routing flexibility. - **Pre-commit Workflow Stability:** Configured hooks (Bandit, Mypy) with `pass_filenames: false` to force systematic execution over the full repository context rather than fragmented staged files. +### Fixed + +- **Compatibility**: Restored parity with legacy exceptions and dynamic routing behavior to ensure zero breaking changes for existing SDK consumers. + ## [1.6.0] -

**Enterprise Runtime Security:** Added opt-in PEP 578 Audit Hooks (`sys.addaudithook`) managed via the new `Config` class attribute `enable_security_audit` to monitor runtime network events (`mailjet.security.*`) for SIEM/SecOps compliance. -- **Path Traversal Mitigation (CWE-22)**: Implemented strict path segment sanitization in `Endpoint` and `guardrails.py` using `urllib.parse.quote(safe="")` to prevent directory traversal via dynamic ID inputs. -- **Runtime Security**: Centralized and hardened `SecurityGuard.sanitize_segment` to neutralize potential CRLF injections and path traversal attempts across the entire request stack. -- **Supply Chain Security:** Hardened the GitHub Actions validation pipeline by implementing Google's `osv-scanner` and separating `pip-audit` into an independent strict security job. -- **Static Analysis Hardening:** Expanded Semgrep scanning targets to include the `p/insecure-transport` extended query suite and wired internal Bandit configuration (`-c pyproject.toml`) directly into CI workflow checkpoints. -- **Automated Fuzzing:** Integrated `Atheris` (libFuzzer engine) code coverage suite into development workflows, exposing a unified orchestration entry point (`manage.sh fuzz_all`). -- **Secret Hygiene:** Updated repository infrastructure defaults (`.gitignore`) to strictly reject the accidental stage or commit of local private keys (`*.key`). +- **Enterprise Runtime Security:** Added opt-in PEP 578 Audit Hooks (`sys.addaudithook`) via `Config.enable_security_audit` to track runtime network events. +- **Path Traversal Mitigation:** Implemented strict input sanitization using `urllib.parse.quote(safe="")` across endpoints to block directory traversal attacks. +- **Centralized Security Control:** Centralized path and string checks inside `SecurityGuard.sanitize_segment` to stop CRLF injection and traversal attempts across all requests. +- Pipeline validation: Added Google's `osv-scanner` and turned `pip-audit` into a strict, standalone task inside the GitHub Actions pipeline. +- Static analysis: Expanded Semgrep scans to cover insecure transports and connected the custom Bandit configuration file straight into CI gates. +- Fuzz testing: Integrated the `Atheris` coverage-guided fuzzing tool into development routines via a unified `manage.sh fuzz_all` script. ### Added -- **Registry-Based Routing**: Implemented O(1) immutable routing registry (`ROUTE_MAP`) for static endpoint resolution, significantly reducing dynamic attribute lookup overhead. -- **TemplateContentBuilder**: Introduced a dedicated fluent builder for `Content API` payloads, enforcing schema correctness with fail-fast validation. -- **URI Templating Engine**: Added a robust path interpolation engine in `Endpoint` to handle complex multi-level REST resources dynamically without handler proliferation. -- **Telemetry Infrastructure**: Enhanced internal telemetry extraction for better structured logging of API request payloads. -- **Domain Configuration:** Extracted configuration logic out of the monolithic client layout into a dedicated `Config` structure (`mailjet_rest/config.py`) to safely isolate runtime parameters. -- **Testing Ecosystem:** Segmented the testing footprint into clear execution topologies: `tests/unit/` (100% offline via mock patches), `tests/integration/` (live network testing), `tests/regression/`, and `tests/fuzz/` (Atheris mutations). -- **Error Boundaries:** Introduced a dedicated `errors.py` module containing explicit, domain-specific leave exceptions (`ValidationError`, `MailjetAuthError`, `ApiRateLimitError`, etc.) to avoid catching bare exceptions. -- **Type Definitions:** Added a structured `types.py` layer to eliminate MyPy "Type Blindness" across private utilities and dynamic client trackers. +- **Static O(1) Routing:** Replaced procedural dynamic routing with an immutable `ROUTE_MAP` registry to process endpoints instantly and remove lookup overhead. +- **Zero-Leak Sandbox Mode:** Introduced a `dry_run=True` client initialization parameter to safely mock mutations locally without sending real network traffic. +- **Lazy Pagination:** Added a `.stream()` generator method on endpoints to handle records automatically without manual pagination loops. +- Fluent payload builders: Introduced `MessageBuilder` and `TemplateContentBuilder` to easily construct and validate complex API requests. +- Custom domain exceptions: Created a dedicated error layer with clear exceptions like `ValidationError` and `MailjetAuthError` to eliminate broad exception silencing. +- Explicit type safety: Developed a complete `types.py` definition layer to remove MyPy type blindness across internal utilities. +- URL templating engine: Added a dynamic path interpolation engine to handle multi-level REST endpoints smoothly. +- Testing topology: Split tests into separate, dedicated environments for unit (fully offline), integration (live), regression, and fuzzing suites. +- Structured telemetry: Enhanced internal logging to record structured API request payloads clearly. ### Changed -- **Performance Optimization**: - - Migrated from procedural dynamic routing (`__getattr__`) to O(1) static lookups. - - Refactored internal string manipulations to use native Python methods, reducing cold-boot latency by ~29ms. - - Optimized memory footprint by enforcing `__slots__` across core infrastructure classes (`Client`, `Endpoint`, `Config`). -- **Configuration**: Standardized `Config` structure and moved internal type aliases to `types.py` to prevent cyclic import dependencies. -- **Dependency Management**: Updated `pyproject.toml` to optimize `ruff` linting and import grouping (isort). -- **Architectural Decomposition (SRP):** Refactored the bloated `client.py` component, shifting single-responsibility concerns into individual domain files (`builders.py`, `config.py`, `endpoint.py`, `errors.py`, `types.py`). -- **Endpoint Routing Interface:** Relaxed the internal route handler signature `_route_data` inside `endpoint.py` by converting the explicit name identifier to an optional parameter (`_name: str | None = None`) to increase routing flexibility. -- **Pre-commit Workflow Stability:** Configured hooks (Bandit, Mypy) with `pass_filenames: false` to force systematic execution over the full repository context rather than fragmented staged files. +- **Architectural Refactoring:** Split the monolithic core file into single-responsibility modules and deployed `__slots__` across core objects to optimize the overall memory footprint. +- Internal performance tuning: Refactored core string operations to reduce cold-boot overhead by roughly 29ms. +- Signature flexibility: Relaxed internal route handler parameters to support optional name identifiers. +- Pipeline workflows: Configured pre-commit hooks to force validation over the entire repository context instead of only checking staged file fragments. +- Infrastructure updates: Upgraded core GitHub Actions dependencies to modern release versions and aligned workspace triggers. +- Development docs: Updated optimization benchmarks and performance profiling instructions. ### Fixed -- **Compatibility**: Restored parity with legacy exceptions and dynamic routing behavior to ensure zero breaking changes for existing SDK consumers. +- Legacy compatibility: Restored parity with old exceptions and dynamic routing mechanics to keep integration completely seamless for existing users. ##
