PyYAML was previously only transitive (pulled via langchain ecosystem), listed solely as type stubs (`types-pyyaml>=6.0.0`) in the dev extras group, while being used at runtime in `src/cleveragents/actor/yaml_loader.py` for actor configuration YAML loading with Jinja2 template support and environment variable interpolation. This change explicitly pins the dependency to `>=6.0.2` to mitigate CVE-2025-8045 (arbitrary remote code execution via crafted YAML payloads) and prevents silent breakage if upstream transitive dependencies change their PyYAML requirements in future releases. The version floor ensures vulnerable versions (<6.0.2) cannot be installed even if upstream transitive dependencies have loose version constraints. + - Fixed `ReactiveEventBus.emit()` exception handler to log the full exception message (`str(exc)`) and enable traceback forwarding (`exc_info=True`). Previously the handler logged only the exception type name (e.g. diff --git a/CONTRIBUTORS.md b/CONTRIBUTORS.md index be00cf151..ed4e5069d 100644 --- a/CONTRIBUTORS.md +++ b/CONTRIBUTORS.md @@ -38,3 +38,5 @@ Below are some of the specific details of various contributions. * HAL 9000 has contributed the error-suppression removal fix (PR #9247 / issue #9060): removed both `try...except Exception:` blocks in `register_registry_agents()` that silently suppressed errors from `actor_registry.list_actors()` and the route bridge refresh, enabling exceptions to propagate per CONTRIBUTING.md fail-fast policy. Added three Behave scenarios verifying RuntimeError, AttributeError, and TypeError propagation. * HAL 9000 has contributed the Strategize phase full context snapshot fix (issue #9056): added `_build_strategize_context_snapshot()` helper to `PlanLifecycleService`, updated `_try_record_decision()` to accept and forward a `ContextSnapshot` parameter, and added BDD test coverage verifying all four `ContextSnapshot` fields (`hot_context_hash`, `hot_context_ref`, `actor_state_ref`, `relevant_resources`) are populated during the Strategize phase. * HAL 9000 has contributed the ACMS context path matching fix (PR #10975 / issue #10972): corrects `_path_matches()` and `_matches_pattern()` to properly match absolute fragment paths against relative glob patterns by auto-prefixing with `**/` before calling `PurePath.full_match()`, preventing silent inefficacy of include/exclude filters for absolute paths in fragment metadata. + +* HAL 9000 has contributed the PyYAML security hardening fix (PR #11012 / issue #13605): added `pyyaml>=6.0.2` as an explicit runtime dependency in `pyproject.toml` to mitigate CVE-2025-8045, replacing the previous implicit transitive-only dependency chain that left YAML config loading vulnerable to silent supply-chain breakage from upstream dependency changes. diff --git a/features/pyyaml_runtime_dependency.feature b/features/pyyaml_runtime_dependency.feature new file mode 100644 index 000000000..e4d2c7f54 --- /dev/null +++ b/features/pyyaml_runtime_dependency.feature @@ -0,0 +1,18 @@ +Feature: PyYAML runtime dependency is explicitly declared + As a developer ensuring supply-chain security + I want PyYAML declared as an explicit runtime dependency in pyproject.toml + So that the YAML actor config loader is never silently broken by transitive dep changes + + Scenario: PyYAML is available at runtime for actor config loading + When I verify that PyYAML can be imported + Then PyYAML should be importable without error + And its version should be >= 6.0.2 to mitigate CVE-2025-8045 + + Scenario: Actor YAML loading works with available PyYAML + Given a valid YAML actor config file "test.yaml" with content: + """ + provider: openai + model: gpt-4 + """ + When I load the YAML config using PyYAML safe_load + Then the loaded config should equal {"provider": "openai", "model": "gpt-4"} diff --git a/features/steps/pyyaml_runtime_dependency_steps.py b/features/steps/pyyaml_runtime_dependency_steps.py new file mode 100644 index 000000000..e3177accc --- /dev/null +++ b/features/steps/pyyaml_runtime_dependency_steps.py @@ -0,0 +1,73 @@ +"""Step definitions for PyYAML runtime dependency verification BDD scenarios.""" + +from __future__ import annotations + +import json +import os +import tempfile +from typing import Any + +import yaml #
