Ensure third-party artifacts and open-source libraries are verified

Descripción

Ensure third-party artifacts and open-source libraries in use are trusted and verified. Verify third-party artifacts used in code are trusted and have not been infected by a malicious actor before use. This can be accomplished, for example, by comparing the checksum of the dependency to its checksum in a ... Actions permissions (organization, or else the repository) must be allowed_actions "selected" with GitHub-owned actions allowed. Uses the GitHub REST/GraphQL API through gh api (read-only). The repository comes from GH_REPO or the current git checkout (gh's {owner}/{repo} resolution, GH_HOST for GitHub Enterprise Server); the organization comes from GH_ORG (default: the repository owner). Fails when gh is missing or unauthenticated (gh auth login or GH_TOKEN); organization settings and branch protection need an owner/admin token.

Método de auditoría: Comando de shell

shell

command -v gh >/dev/null 2>&1 || exit 1
gh auth status >/dev/null 2>&1 || exit 1
info=$(gh api 'repos/{owner}/{repo}' --jq '.full_name + " " + .default_branch' 2>/dev/null) || exit 1

}
chk "orgs/$O" && { echo compliant; exit 0; }
chk "repos/$R" && echo compliant

Salida esperada: compliant

Cómo se corrige

Método de corrección: Guía o parche de infraestructura

Organization (or repository) Settings > Actions > General > Policies: Allow <owner>, and select non-<owner>, actions and reusable workflows; check Allow actions created by GitHub and list only verified third-party actions.
