Lint AWS CloudFormation templates with security rules

aws-cloudformation/cfn-lint · Infrastructure as Code Security · scanned v1.59.0 (released 2026-10-28) · commit cf5360c6ce4c · last scan 2026-11-02

The scan method changed on 2026-11-02. npm development dependencies and npm-shrinkwrap.json are now scanned; matches on GitHub Actions referenced by a moving tag and on npm packages the repository defines itself are no longer counted; directories such as integration-tests and test-fixtures are excluded as fixtures. Most differences from the previous week below come from that change, not from the projects. Details.

History

SBOM minimum elements

Scored by sbomlyze on the generated source SBOM. A source SBOM usually lacks supplier and hash data, so these scores mostly reflect what the project's manifests declare.

How this report is made

Every Sunday a GitHub Actions workflow resolves each catalog tool to its latest release and runs the checks below. Every tool is installed from its own latest release and verified against its published checksum or digest. Nothing from the scanned projects is built or executed; release binaries are analyzed as files.
