- passNot deprecated: not marked as deprecated (support period and updates)
- missingActively maintained: Scorecard Maintained 0/10 (security updates for the whole support period)
- passSecurity policy: Scorecard Security-Policy 10/10 (Annex I, Part II: coordinated vulnerability disclosure policy and contact address)
- passLicence declared: MIT (component documentation and licence notices)
- missingCode review before merge: Scorecard Code-Review 2/10 (secure development process (Annex VII, development and vulnerability handling processes))
- missingCI workflow hygiene: Dangerous-Workflow 10, Token-Permissions 0 (integrity of the build and update chain)

pyyaml 6.0.3 is the current default version of this PyPI package, published on 2025-09-25. The registry lists 59 versions in total and the licence declared is MIT. The source repository is yaml/pyyaml with 2,950 stars.
The OpenSSF Scorecard for the repository was last computed on 2026-08-24 and gives an overall 4.8/10. Signals that are not in place today: actively maintained; code review before merge; ci workflow hygiene; signed releases or provenance.
As of 2026-10-05, deps.dev lists no known advisories for this version. That is a snapshot and not a promise: new advisories can be published at any time.
If you ship a product that includes pyyaml, the Cyber Resilience Act expects you to know which components you ship, to follow their vulnerabilities and to exercise due diligence on third-party components (Annex I, Part II and Article 13). In practice: list pyyaml 6.0.3 in your SBOM with its package URL pkg:pypi/[email protected], watch for new advisories, and keep the upstream security contact in your vulnerability handling process. With several signals missing, consider whether a better-maintained alternative exists.

Package and version facts, licences, advisories and provenance: deps.dev (generated data under CC BY 4.0; advisories from OSV). Repository signals: the OpenSSF Scorecard. We read them on 2026-10-05 and show them without scoring the people behind a project. The nine signals are our selection; every signal could be read for this package.
